Internal Fault

Internal fault

Checking the intake and exhaust system




If the malfunction is intermittent, it means that the malfunction has been registered at an earlier time but the malfunction no longer remains. Intermittent faults may be due to interference at start up of the control module or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs.
If the diagnostic trouble code (DTC) is permanent:
- Check the intake and exhaust system. Check for blockages.
- Check the intake system for leakage.
- Check the inside of the throttle body (TB). Check for contamination. When the throttle body (TB) is contaminated, the air flow to the engine is impaired and diagnostic trouble code (DTCs) or fault symptoms can occur.
Remedy as necessary.
