P00A2 Oldsmobile Eight Diagnostic Trouble Code
P00A2 Oldsmobile Eight code definition:
P00A2 is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Oldsmobile Eight.
P00A2 Oldsmobile Eight is triggered when the bank 1 camshaft position sensor doesn't match the signal from the crankshaft position sensor. This is because the barometric pressure sensor is part of the MAF sensor. Sometimes, the MAF's sensing wire can accumulate and get covered with dirt, dust and/or oil residue, which can also lead to the error code.
Symptoms
Symptoms of a P00A2 Oldsmobile Eight diagnostic trouble code may include:
- Faulty or damaged wiring
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- Poor fuel economy
- If the DPF is not cleared the ECU will revert to the "Limp Home Mode" until the situation is corrected

Possible Causes :
- A large air leak at or near the number one oxygen sensor would also cause a lean mixture.
- Faulty IMRC actuator relay (if equipped)
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.
