PACCAR MX (2004 Emissions) Fault Code: P2266 Water in Fuel – Voltage Too Low or Short Circuit to Ground on ECU (D420) Pin (A49)
Posted by Diezel Solutions on
PACCAR MX (2004 Emissions) Fault Code: P2266 Water in Fuel – Voltage Too Low or Short Circuit to Ground on ECU (D420) Pin (A49) SET CONDITIONS:This DTC is set when the ECU detects a lower voltage than expected on the signal or control circuit of the ECU. DIAGNOSTIC CONDITION:This diagnostic runs continuously when the engine is running. CORRESPONDING OBD READINESS MONITOR:None RESET CONDITION:This DTC changes to inactive when the fault is no longer detected. To validate the repair, monitor the water in fuel sensor signal with the diagnostic service tool. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive or operate the...
