Possible Causes
- The value of the signal measured by the engine control module is not plausible given the operating conditions
- Manifold absolute pressure and temperature sensor circuit, for short circuit to ground, short circuit to power, open circuit, high resistance
- Intake manifold air leak
- Throttle adaption failure
- Blocked air filter
- Engine breather leakage
- Carbon obstruction around throttle blade
- Manifold absolute pressure and temperature sensor failure
- Damaged catalytic converter
