Experiencing Failing Coils?
larrycrilley » I have a 2001 v70xc and the check engine light came on and it had began running rough. I checked here on this forum and it seemed like a good cleaning of the MAF sensor might help. I used the cleaner (CRC MAF cleaner) and reassembled every thing and the CEL & rough idle continued.
I came back to the forum and took the advice to a take the car to AutoZone to have the codes read. The codes were P1171 and P0303. P1171 is for the MAF sensor and P0303 is a misfire on the #3 cylander.
My Questions are:
1). Is the misfire due to the sensor since they both happened at the same time?
2). Should have the codes been reset after the cleaning? Would this eliminate the CEL & rough running?
3). Do I go for the new sensor then reset the code?
4). How do I reset the codes?
5). Is there more I should know?
larrycrilley » I swapped out the the coil ($75.00 dealer part) and my problems were solved. I cleaned the MAF sensor and it was no longer an issue. Went to my local Autozone and reset my light. All is well with my wonderful XC70!
Bonus! More on The Volvo XC70
At its introduction, the second generation V70 XC received a major upgrade. It featured better ground clearance of 8.2 in (210 mm) thanks to a raised suspension, different bodywork with unpainted bumpers and fender extensions, and AWD as standard. An interior grab handle for the front passenger was installed only on this model. Early V70 XC featured special rear view mirrors, a feature that was discontinued after 2003.
Engine and gearbox choices were limited. Only the 2.5L low pressure turbo, or the D5 diesel engine with either a 5-speed manual or 5-speed automatic transmission were available. No diesel version was offered for the North American market.
For 2003 the model was renamed the XC70, in keeping with Volvo’s newly introduced XC90
