DDEC VI SERIES 60 TROUBLESHOOTING GUIDE
[a] If the resistance is less than 5
Ω
, repair the short between pin 109 of the 120–pin
MCM connector and ground. Refer to section 15.3.1.1.
[b] If the resistance is greater than 5
Ω
, repair the open circuit between pin 3 of the
EGR Delta P Sensor harness connector and pin 109 of the 120–pin MCM connector.
Refer to section 15.3.1.1.
15.3.1.1
Verify Repairs

15.4 SPN 411/FMI 4
This diagnosis is typically EGR Delta P Sensor short to ground.
15.4.1
Short to Ground Check
Check as follows:
1. Disconnect the EGR Delta P Sensor.
2. Disconnect the 120–pin MCM connector.
3. Measure the resistance between pins 1 and 2 of the EGR Delta P Sensor.
[a] If the resistance is greater than 5
Ω
, go to step 4.
[b] If the resistance is less than 5
Ω
, repair the short between pins 103 and 117 of the
120–pin MCM connector. Refer to section 15.4.1.1.
4. Measure the resistance between pins 2 and 3 of the EGR Delta P Sensor.
[a] If the resistance is greater than 5
Ω
, go to step 5.
