I recently did a 6 speed swap on my 03 TL and the current 3 issues I have are 3 codes. P0386, P0141, and P0450. I’m thinking it’s a wiring issue. The issue that I’m most concerned about is the P0450 concerning the Evap. I’m thinking it’s the FTP sensor and that I might have wired it wrong. I believe there’s suppose to be a certain voltage? Has any one encountered this while doing the 6 speed swap and have a solution to it? Yes I’m new to Acurazine. Thanks y’all.

Since this is a topic/technical issue which will require replies and discussion, this thread has been moved to the model specific forum.

Just an FYI. When dealing with the P0386=Crankshaft Position Sensor B, located on the Transmission Bell Housing on the CLS6-speed manual, also check the pulley side CRK Sensor A. It's been known for sensor A & B together to cause problems for swappers even though the other throws the code..
Figure I'll ask just to be sure, but you are using the CL-S6 manual ECU right? If so, there are a couple wiring harnesses that need to be modified to match all the stuff going to the back of the car.
To add on, I’m using the CLS6 Ecu and wire harness to the engine. Everything inside the cabin is the TL wiring that’s why I’m thinking that is the issue. I have the diagram and have been going back and forth on the TL and CL ECM/PCM. 😫 it’s like I’m almost there but not yet. Again I am more worried about the p0450 code because that’s probably related to to the FTP wiring. Fuel tank pressure sensor. The TL and the CLS6 have different voltage. One seems to require ground but the other doesn’t. Thanks again.
Why would you think it's okay to just use the manual engine wire harness? You will have to swap a bunch of other stuff. Read the last post on the following thread for some more info.
I got rid of all the other codes except for p0386. Car starts and drives fine but the code is still on. I’m just confused because if it’s the CKP sensor it wouldn’t start at all. Wouldn’t it? Will update soon.
In my case I used an Auto j32a2 motor. I thought I had swapped the necessary parts over to make it run like the manual version but I had forgot one thing. The crankshaft gear. To fix the CKP code I swapped out the Crankshaft Gear with the manual version. They are totally different. The Manual one has more teeth on the back. At the time I was running the Auto version and it threw a code.
I forgot to take a picture of them side by side because I was too anxious to put everything on. I managed to take a pic of the auto one after installing the manual one. Again, the manual one has more teeth. Waaaaaay more at the back of the gear where the CKP sensor is suppose to read it. Attached is the Auto one.
Like yours above, here is another good picture of a timing belt drive pulley (fewer reluctor teeth) from an 'automatic' trans engine. This one is from a J35A3. Notice that there is no TB stopper plate or a locating flange bolt 'boss' on the J35A3 oil pump assembly.

Very descriptive. I like it. A way better explanation then mine. But yeah my codes gone so now all I’m left with is smog and registration. And my future plan is to build the old block and stroke it. 👍

To say the least, thanks for updating your thread.
Your mistake, though probably rather frustrating for you, through painstaking reexamination of your steps, was found eventually and rather inexpensive. As a result, you found joy.
I've seen individuals, come on this forum, attempt to 'swap' an auto J32A2 engine, made compatible to run with a CL-S6 ECU & harnesses, into Accords and such.
The problem is, is that they use a 3G 04-06 TL-6 manual transmission and have crank sensor problems. Reason being is that particular 6 speed manual does not have the clutch case crank sensor the CL-S6 ECU needs to talk with. I believe there are 'standalone' alternatives to 'work around' that miscalculation; however, they are probably not inexpensive when on a budget.
So I thought everything was fine and dandy and took it for a drive to get it ready for smog. Then this p0452 code came on for FTP sensor low input. My work around for that was adding resistors to get the voltage up to spec, but that didn’t work. I heard people grounding it but idk where to ground it to? Any ideas?
