This thread documents that the P0106 code is often resolved by throttle body cleaning, not MAP sensor replacement. Saves users about 250 USD. Specific to the NA 2003 and 2004 Volvo P2 models. jkatz: Two years ago I bought a 2003 V70 FWD (no turbo) and I was getting an intermittent CEL that would come […]
MVS Volvo Forums member emtbjb has a 1998 V70-XC that will not start. Many times, a no-start condition is a fault with the camshaft position sensor. In fact, it’s often the top thing to look for, after the very obvious culprits have been eliminated as causes. I am testing the camshaft position sensor with a […]
