I have an '06 Coupe with 154k miles. Last week while on my way from So Cal to Texas I stopped to fuel up and noticed a rough idle and service engine soon light on. Didn't think to much of it because it happen once before about 4yrs ago after I put in a fuel treatment. Then the DTC was maf sensor. Changed it and fixed. Now back to last week, fueled up and kept driving. Drove fine. Set the cruise at 75 climbing a long hill. All of a sudden the car went into limp mode. Got it to the shoulder and it shut off on me. Got it towed to town 60 miles away and got a room. Next day I scanned it and got p0011, p0340 and p0345. So I changed out both cam sensors with Hitachi sensors and still no start. Fuel pump is priming, BTW fuel gauge was working and reading correctly oddly enough which it never read correctly before. Now it's pegged to the left side of empty and when I turn the key on it'll read empty. Tank is full. Pulled a plug out and no spark. Checked for good grounding. Checked for resistance on sensors. Checked for corrosion on ipdm because my battery tray had water in it. Cleaned all ipdm terminals with rubbing alcohol. Checked all fuses and relays with meter. All 3 fuse box locations. So right now I'm just waiting on a crank sensor. Am I missing anything else to look for? I'm really puzzled by this. Any suggestions will be greatly appreciated.

 

Check the tac wile cranking. If it doesn't move, you need to replace the crank sensor under the car, or check the wiring and connector. I believe it is located on the driver's side where the engine block and the bell housing meet. Go to the service manual (attached link) to confirm the correct location.

I've got a crank sensor on order, just waiting for it. I also checked the tach on the scanner in live mode while cranking, it reads 175 rpm . But on the gauge I see no movement. Thanks for the reply btw.

 

Any update?


 

Same thing happening to me. Any update?

 

Timing chain broke due to guide getting brittle. I bought a JDM engine and am in the final stages of swapping in out. Check your chain tensioner and compression.
