Symptoms
Symptoms of a P00A4 Lancia Hit diagnostic trouble code may include:
- Poor acceleration
- Cherry red hot catalytic converter
- Possible spark knock (detonation / pre-ignition)
- 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
|
Possible Causes :
- Defective ECU strategies or components will prevent proper regeneration
- The Mass Airflow sensor is a hot wire that senses the volume of air entering the intake manifold. The computer uses this information to control fuel mixture.
- A large air leak at or near the number one oxygen sensor would also cause a lean mixture.

Common Misdiagnoses
- Vehicle Speed Output Circuit Problem

Repair Processes :
With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
Look for rubbing, scraping, bare wires, worn spots or melted plastic connectors. Pull the connectors apart and carefully look at the terminals (the metal parts) inside the connectors.
