fault code P1315


Recommended Posts

Misfire, Emission related, signal implausible cly 1-6 is the only code i got after doing to work to my MY99 boxster

The plan for the day was replace the sensor and adjust the the timing for code P1324 as well as new oil with a filter.

* note * huge performance gains with the car by fixing this problem

now theirs a new problem my car may run like it never has before

i have the code P1315

i have checked the spark plugs there all in good condition i got them new about 3 weeks ago and i changed 2 coil packs on the passenger side

still have the same code and problem which is cold start really rough ideal and slight pop/ back fire, car warms up and it stops but still slight rough idle.

any pointers

P 1315 refers to cyl.3 misfire (bank 1 - pass. side LHD 986/7) check the coil connector for proper fitting and don't forget to inspect the #3 injector + connector as well. The misfire concept encompasses more than ignition problems only.

so turns out we pull out the coil pack with closer inspection has some tiny cracks on it so i garbed and extra one that was good, also i pulled the plug out to look at it and turns out one side was bent! So i bought a new one and now the car is smooth as silk!
