Check the continuity and insulation to earth of the following connections:
Injection computer 48-track brown connector B, track J2 Track 6 EGR valve.
Injection computer brown 48-track connector B, track F4 Track 2 EGR valve
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
EGR valve with a square connector:
Measure the resistance of the EGR valve position feedback potentiometer between tracks 2 and 4.
If the resistance measured is not between 3.9 k
Ω < X < 9.1 kΩ at 20˚C, replace the EGR valve.
EGR valve with a flat connector:
Replace the EGR valve.
If the valve is jammed or irrevocably seized, replace the EGR valve.
When replacing the EGR valve, run command SC036 Reinitialise programming and select EGR valve to
reinitialise the EGR valve offsets (see Replacement of components).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESNone.
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Check for continuity and insulation to + 12 V on the following connections:
Injection computer brown 48-track connector B, track J2 Track 6 EGR valve.
Injection computer 32-track grey connector C track C2 Track 4 EGR valve
Injection computer brown 48-track connector B, track F4 Track 2 EGR valve
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Ensure the presence of + 5 V on track 2 of the EGR valve.
EGR valve with a square connector:
Measure the resistance of the EGR valve position feedback potentiometer between tracks 2 and 4.
If the resistance displayed is not between 3.9 k
Ω < X < 9.1 kΩ at 20˚C, replace the EGR valve.
EGR valve with a flat connector:
Replace the EGR valve.
If the valve is jammed or irrevocably seized, replace the EGR valve.
