Symptom:
P-0401 EGR SYSTEM FAILURE
When Monitored and Set Condition:
P-0401 EGR SYSTEM FAILURE
When Monitored: With engine temp > than 82 degrees C (180 degrees F), ambient temp
> 4 degrees C (40 degrees F), engine in closed loop, O2 Sensor operational, engine under a
steady load with throttle open, and O2 Controller not at or near its limits.
Set Condition: If all conditions met, turn EGR off & on. O2 Snsr Sig is monitored for
change in output sig. If no major change or too much change, flag is set. Repeat test up to
3x in run cycle (2 trips). If fails every time, code sets. If any pass, diags are suspended.
POSSIBLE CAUSES
EXHAUST LEAK
INTAKE MANIFOLD RESTRICTED
EGR BACK PRESSURE TRANSDUCER DEFECTIVE
EGR VALVE ASSEMBLY DEFECTIVE
EGR VALVE ASSEMBLY MOUNTED INCORRECTLY
EGR SYSTEM FAILURE DOES NOT REOCCUR
EGR TRANSDUCER LINE BLOCKED
EGR VALVE ASSEMBLY DIAPHRAM DEFECTIVE
VACUUM SUPPLY TO EGR SOLENOID INADEQUATE
