Q: Check engine light

asked by on December 14, 2016

Just had car in for service, had oil gasket leak repaired as well as a O2 sensor. On the way home check engine light comes on again.

Get home and pull out the OBD code reader and stored code is reading P0325 - Knock Sensor 1 Circuit Bank 1 or Single Sensor. Pending Codes: P2187 - System Too Lean at Idle Bank 1, as well as the above mentioned code.

Could these codes be related to the above repair work done? Any other advice on these codes is appreciated.

My car has 93500 miles.
My car has an automatic transmission.
