ECM-23X0 INJECTOR X
SIGNAL MISSING - INTERMITTENT FAULT

Checking cables and connectors



Check injector connector for contact resistance and oxidation according to [1][2]Checking Wiring and Terminals. Intermittent Faults and loose connections according to [1][2]Checking Wiring and Terminals. Intermittent Faults

Check cable between injector terminal 2 and control module:
- # A16 (# A16) (ECM 2310)
- # A34 (# A34) (ECM 2320)
- # A15 (# A15) (ECM 2330)
- # A33 (# A33) (ECM 2340)
- # A14 (# A14) (ECM 2350)
and power supply between system relay terminal 3 and injector terminal 1 for an intermittent open-circuit according to [1][2]Checking Wiring and Terminals. Intermittent Faults
