Question

Volkswagen Jetta with engine code P0312 code? what does the code mean?

Answer 1

Hi there

This is a generic OBDII code for a cylinder 12 misfire. It seems unlikely this is the case on a VW jetta, so I would start by rechecking the code. If it happens to be P0302, this code is for a #2 cylinder misfire.

Answer 2

P0312 VOLKSWAGEN Code - Cylinder 12 Misfire Condition
