Yesterday Morning I, was driving my 2006 Acura TL manual transmission with 186k miles. The car randomly just died while on the highway. Pulled over had it towed home checked the check engine light codes and came back with.

-Code
P0340

-Pending codes are
P0154
P0134

After the car died, it just doesn't want to start. It turns over but doesn't start.

P0340, not sure if the car would shut down because of the crankshaft sensor going bad.

Any thoughts or where I should start? Charged the battery and it is fine. When I tried to spray some starting fluid I noticed that the throttle body is not opening when I push on the gas.

Not 100% sure but if I remember correctly all the dash lights came on when it turned off.

Thanks for the help in advanced!

 

if crankshaft sensor is bad, car will shut off. or stall

 

How's your positive battery terminal?

 

Might want to give this a go.

Looks fine no corrosion or anything

 

the crankshaft is what spin in the block. if sensor isnt reading correctly, crankshaft wont spin...car wont turn on

 

Are you sure? Try replacing the + battery cable. At this age its likely corroded internally. I had to replace mine last year.

Do you happen to know where the sensor is?
my OBD reader says its.

Crankshaft Position Sensor "A" Circuit Bank 1 or Single Sensor.

 

I'll have another look at it.

 

OP, when I search that code for your '06 TL-S6 I come back with 'Camshaft Position Sensor No Signal'. You may want to double check the code accuracy again.

#14 on the link below is the Camshaft TDC sensor for your TL-S6

This thread has info on the above codes:

I always thought if you prevented the crankshaft from spinning the car would rotate around the axis of the main bearings. Maybe I've over thought the process.

 

Thanks man I called the Acura Dealer to get the part number they gave me 37840-PGE-A11. #14 Is the correct sensor. Placed the order for the sensor now I need to wait for it. By any chance do you think I will have to remove the timing belt to get to the sensor? Because in the in schematics it looks like I do.

 

Yes.

If the TDC Sensor replacement repair procedure for your '06TL-S6 is similar to the '03CL-S6 (that's what I drive) you or your mechanic will have to remove the TB and the appropriate cam gear to get at it for replacement. The attachment below should give you a pretty good idea of what to expect, keep in mind though, that the TDC Sensor replacement on the attachment is for an '03CL-S6.

Good Luck!

 

Just want to post on what the problem was. So that if anyone ever googles and finds this.

The timing belt on the car broke and the car is now running again just fine.

 

Is it running, or running good?

Im surprised that engine survived broken belt, and cranking.

 

Holy hell, how did it not trash the engine?? If the engine wasn't trashed when it broke, how did it survive subsequent beating when you tried to crank it with the starter? Something isn't right here.

Had the timing belt ever been replaced before?

 

When I accidentally forgot to install the little pin to the crank pulley and tried to crank, the engine instantly seized

 

Glad to hear you got your car running again, but the diagnosis doesn't seem right. Interference engines don't normally do well after the timing belt breaks.

Agreed +1

Agreed +2

 

I have to agree with the last posts. No way the timing belt broke and didnt trash the valves at least. Anyway at least he got it running again.

 

Yes car is running as it should right before the belt broke off. Now before this happens again, I need to get the timing belt done on my other M/T 2006 Acura TL. On the TL that the belt broke off I don't know if it was ever changed, as I got it when it had 140k so I would assume they didn't. Sense the belt didn't last up to 200k I'm surprised myself it survived

 

you seem to be missing the point. Broken timing belt = crushed valves. Did you see the broken timing belt? As in did the mechanic call you into the mechanics bay and go "here's your problem!"

 

If the timing belt broke and the engine was spun, some of the valves at a minimum tapped the top of the pistons. Some people it is very obvious immediately and their engines run rough or have a miss....for others, the oddities don't show up for a little while longer...but they do show up. A bent valve is a bent valve...it will eventually cause some issues.

 

You guys were correct, Do you guys know if the A/T Acura TL motor will work fine with a M/T Acura TL

 

It's doable but not plug and play.

 

Huh? What? It finally cratered?

 

the motor is identical except for one small breather valve that runs accross the engine that is easily swapped and maybe the wire harness too. Watch Eric the Car Guy's 3 or 4 part video on the 3.2TL engine swap, he does a A/T & M/T swap. Find a new mechanic because he should not have done a timing belt job on a busted belt.

 

it is plug and play.
i'm rocking an auto engine in my 6MT.
mechanic will just have to plug up extra coolant lines...

 

Anyone by any chance know a good mechanic out in the Bay Area Of California. It's hard to find a good trustworthy mechanic.

Maybe I was confused with an AV6 swap?
