No conclusive reason for P0336
No conclusive reason for P0336
Alright Acura guys here's my dilemma:
I recently performed a J35A3 block swap on my 2003 Acura CL-S 6mt. J32A2 heads on J35A3 block. New timing belt & water pump. Swapped over all manual sensors and parts (crank gear & tooth plate) from my J32A2 block. P2R clutch disk, LUK pressure plate & AASCO lightweight flywheel.
Fired up beautifully. CEL came on as soon as I gave it gas. P0336 for crank position sensor 1.
Replaced crank sensor. Performed relearn. Timing is right. My Acura dealership has no clue.
I'm running out of options and ideas. My final thought is that the flywheel isn't right. I've googled it, searched our forums along with and j32a.com. I've seen that in a few cases it has been the flywheel screwing everything else up.
Anyone care to chime in with a thought?
Thank you.

Was there any P0336 problems running this set-up 'before' you did your J35A3 engine swap?
Just curious, before you swapped the J32A2 heads to the J35A3, did you check them for warpage? As shown with the 'precision straight edge' process in the Helm's or by a machine shop.
Thanks in advance.

Zeta,
I did not have the P2R disc, LUK pp & AASCO flywheel on until I did the block swap. Previous clutch setup was stock style parts.
No P0336 codes present until initial start up after swap was completed.
Heads were inspected by my Acura tech before they were attached to block.

Thanks for the response.
The only 'testing' I can find in the Helm's in regards to the P0336 code is on page 11-117; Range/Performance problem in CKP Sensor Circuit. If you don't have the CL Manual, you can supposedly download it from the thread below.
https://acurazine.com/forums/second-...-776021/page2/
The testing carried out on page 11-115 appears to be a test for 'continuity' and such with 'ground' or PCM involvement. Looking at the statement below from the OP in the thread that thoiboi provided, it appears that is potentially how his mechanic work out his problem.
Wonder if the Acura folks performed this test on your car? A wire on the harness connecting to the CRK sensor my have accidentally become loose or twisted as part of the J32A2 extraction and subsequent install of the J35A3. Or there is a ground problem with the harness connector,
Otherwise, your hunch also could be correct as well about having issues with the LW flywheel, since it is all new as a result of your engine swap. That's the best I can offer. Good Luck.

Zeta,
They did test for continuity and no problems were found. They are stumped. I'm going to replace crank sensor on bellhousing as a final easy solution before i rip everything apart again. When i removed/reinstalled motor I made sure to have harness well out of the way.
Teh CL,
No possibility of that. I still have my auto crank gear and sensor sitting in my garage. I made sure I had it well away from my work area lol.

On to the flywheel. Are you leaning toward one or more of the crank triggers, as displayed on the pics below, being the issue?
I presume the clutch/PP engages currently with no binding/grinding problems with the engine running? Just throwing this out there, and wondering/trying to think HOW the triggers could cause the problem unless they were somehow not lining up/close enough with the sensor as the flywheel spins.
Will be interested to hear about what is found if replacing the CRK sensor again does not give you any joy.
Zeta,
If I had to assume, I would say yes to the crank triggers on flywheel.
The clutch engagement is smooth, shifts normally, better than stock. It starts up easily, runs smooth and doesn't make any abnormal noise. I just can't rev past 2500rpm. It's killing me, that j35 purrs so sweetly.

lol, I can hear the anguish in your text. The only other on here, that I can recall at this time, whom has a J35A3 CL6-speed Type-S is hitek9, so you guys are a rare breed. Let's hope that it is only the sensor and there will be no need to drop the tranny for exploratory surgery.

But, it'll get resolved eventually.... have to recoup financially first lol.
Codes P0385,P0386 are in regards to Crankshaft Position Sensor B, which is located on the Transmission Bell Housing on the 6-speed.
The location of CRK Sensor B was identified within the 'Manual Transmission' section of the Helm's manual, specifically on page 13-12 within the "Transmission Removal" sub-section.
Step 12 of that sub-section states to "Disconnect the CKP sensor B connector, then remove the CKP sensor B, and the ground cable." as part of the trans. removal procedure.
Therefore, it is reasonable to assume that your "P0336 Crankshaft Position Sensor A circuit Range/Performance" code is the CKP sensor located BEHIND the crank pulley.
Since the focus has been on the transmission side/flywheel triggers, I was just wondering if you had tried changing out the sensor on the crankshaft pulley side?

Your issue made me think of Rajca. He had the same thing and it was the flywheel.
https://acurazine.com/forums/second-...sensor-864323/
He swapped back to OEM and it was fine.

The next thing is the CRK sensor on the tranny side and/or the triggers on the flywheel, yet there are no P0385, P0386 codes that would indicate either the sensor or the FW triggers are in play to cause your P0336 CRK pulley side code.
You have confirmed, in your answer to teh CL's post, that the J35 lower timing sensor/TB drive pulley was not mistakenly used in lieu of the J32's shown below, so that can't be the problem.
Just throwing this out there, IF the problem still lies on the CRK pulley side per the P0336 code, after you check the tranny side sensor and FW triggers, could the New J32 crank side sensor, somehow?, not be close enough, to the reluctor triggers on the J32 TB drive pulley or could the TB drive pulley itself be damaged? I see the J35 block, above, only allows for one of the bolts to be used in securing the sensor along with the timing belt stopper plate, since there is no 'boss' for the upper bolt at the top of the plate.
P.S.; thanks to teh CL for the pic's above from his conversion thread.

That night when my car wouldn't rev past 2000 rpms the only code I got with my scanner was P0336 Crankshaft Position Sensor A CKT Range/Perf. The next morning when it wouldn't start I checked it a few times and was getting the same exact code, P0336. I would of thought that it should have given me the P0385 or P0386 code, but it didn't. I'll check it again tomorrow to see if anything has changed, but I doubt it.
2ndgentl also got the CRK pulley side P0336 code when his stock clutch pressure plate grenaded and subsequently destroyed his Aasco LW flywheel and tranny side CRK sensor last year.
Adam, I hope the fix you are seeking is successful by changing the tranny side sensor and/or flywheel, as in Rajca's case above.
Because, to add insult to injury, fsttyms1 had the same P0336 code, in the thread below, and he changed out his LW flywheel with a rebuilt one from Aasco and then to an OEM one with no success. To this day it is unknown whether or not he ever resolved the problem.
https://acurazine.com/forums/second-...ed-ecu-949666/
So, in short, if a P0336 appears, not only does one have to address the CRK sensor gear behind the crank pulley, because that's where the ECU is pointing you, you have to also consider whether the tranny side sensor and/or the flywheel could be the culprit, even without the presence of P0385 or P0386 code, or the ECU itself.
So bizarre.

I have a P0336 crank position code. car wont run right. I tested both sensors, both tested fine but i replaced them both anyway. Still wont run. Replaced the crankshaft timing belt gear no change. Swapped out the flywheel with a new one still nothing. Checked the wiring it tested just fine, but i ran new wires just to make sure no change. Last thing to check is the ECU. Anyone have a spare 6 speed ECU (and key) laying around i can use to test with

Zeta,
The timing belt stopper plate was swapped over also. The timing gear and triggers were swapped over from my known good j32a2. Crown Acura installed my ckp sensor, so I would hope when they R&R crank sensor they realized it was for the 6MT lol.
It is such a wild goose chase. My car ran as designed before the block swap. The only thing non-oem that i put on was the Aasco LW flywheel & P2R 6puck. I'm going to take the $100 gamble and replace CKP sensor 2/b with the hope that it resolves the issue. Not holding my breath. I was really looking forward to the LW flywheel but with everything pointing towards it being my true issue, I'm not gonna keep taking everything apart and swapping flywheels.
And GNUTS, thanks for providing that link, I think it may provide my solution.
I've done sooooo much research on this and talked to so many people. Everyone's help is much appreciated.

I am having the same issue code p0336 I have checked all the voltages and grounds to both sensors I changed the sensor under the crank pulley with no luck. I have a 2003 Acura cl s type with 6mt . What is the name of the flywheel side sensor none of the parts stores cane seam to find it or even show a second crank sensor? About to go nuts on this one!

i replaced every sensor, had the flywheel rebuilt (Aasco light weight) which they replaced the crank triggers free for me, swapped to an oem flywheel (went back to Aasco when it came back), tried different ECU, ran new wires to the ECU from the ckp sensors, tdc sensors, (temp to try to see if it was wiring) and nothing worked. I got mad and let the car sit and think about what it had done and one day i went out to move the car and it started up cel was gone and it hasnt come back. Im waiting for it to come back though.
The 3.5 hybrid runs excellent. I can def feel more torque down low. More power throughout the whole power band. I'm curious how well it will do on a dyno compared to the 3.2. It feels like it needs more air in the top end though, so i may upgrade the throttle body & intake piping. My buddy in his 350z can't pull on me.
It's also a lil more rev happy with that flywheel. But I do have some clutch chatter with the P2R 6 puck. It's been a learning curve on properly engaging it lol.

Replaced clutch now cl will not run inless ckp sensor B is unpluged
I recently have bought a 03 cl type s with a M/T 6 speed the oringial J32A2 was swapped for a JDM J32A from 1st owner. To my knowledge all of the right gears and sensors have been swapped from the manuel A2 motor to the J32A but when i had bought the car it had a CEL light of a crankshaft postion sensor B “po386”. Mean while the light was on the car still ran fine no kind of idle issues nor any rpm shifting problems but the light always was on. Droped it off at the dealer and they told me to replace the crank shaft postion sensor A behind crank pulley..had them do so and the light still came back on with the same code. I then replaced the sensor it self along with a new ecu and no difference. went on to have my mechanic scope the sensors and both were fine an seemed to have good wave forms so my mechanic felt that both the position sensors were working just fine which made sense because the Car seems to run fine but the light was still coming on. Next it needed a clutch which i just replaced yesterday with a stage one clutch masters with a brand new dual mass oem flywheel. i go to start the car after replacement and it wont run... now i must unplug the crank shaft postion sensor B by the transmission just for the car to run? It wont rev past two thousand rpms. I am a lost for words with this thing no one can seem to give me a straight anwser with this car iknow it had the cel light on before but it ran completely fine with the light on and all i did was drop the transmission put a new clutch and flywheel in it and now it wont run in less sensor b is unplugged my mechanic said it most likely may be a defect flywheel an that maybe the sensor isnt reading the triggers on the fly wheel correctly any thoughts are welcomed
