PACCAR MX (2004 Emissions) Fault Code: U17A3 Accelerator Pedal Sensor 2 Duty Cycle – Data Valid but Too High on ECU (D420) Pin (B45) SET CONDITIONS:The PCI ECU (D420) detects that the duty cycle of accelerator pedal position sensor 2 is higher than expected. DIAGNOSTIC CONDITION:This diagnostic runs continuously when the ignition is on. 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 accelerator pedal sensors with the diagnostic service tool. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive or operate the vehicle to meet the diagnostic...

PACCAR MX (2004 Emissions) Fault Code: U17A4 Accelerator Pedal Sensor 2 Duty Cycle – Data Valid but Too Low on ECU (D420) Pin (B45) SET CONDITIONS:The PCI ECU (D420) detects that the duty cycle of accelerator pedal position sensor 2 is lower than expected. DIAGNOSTIC CONDITION:This diagnostic runs continuously when the ignition is on. 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 accelerator pedal sensors with the diagnostic service tool. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive or operate the vehicle to meet the diagnostic...

PACCAR MX (2004 Emissions) Fault Code: U17A5 Accelerator Pedal 2 Frequency – Data Valid but Too High on ECU (D420) Pin (B45) SET CONDITIONS:The PCI ECU (D420) detects that the frequency of accelerator pedal position sensor 2 is more than 220 Hz. DIAGNOSTIC CONDITION:This diagnostic runs continuously when the ignition is on. 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 accelerator pedal sensors with the diagnostic service tool. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive or operate the vehicle to meet the diagnostic conditions and...

PACCAR MX (2004 Emissions) Fault Code: U17A6 Accelerator Pedal 2 Frequency – Data Valid but Too Low on ECU (D420) Pin (B45) SET CONDITIONS:The PCI ECU (D420) detects that the frequency of accelerator pedal position sensor 2 is less than 180 Hz. DIAGNOSTIC CONDITION:This diagnostic runs continuously when the ignition is on. 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 accelerator pedal sensors with the diagnostic service tool. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive or operate the vehicle to meet the diagnostic conditions and...

PACCAR MX (2004 Emissions) Fault Code: U17A7 Accelerator Pedal – Sensor 1 and 2 Synchronization Malfunction SET CONDITIONS:The PCI ECU (D420) detects that the accelerator pedal position sensor 1 or 2 does not correspond to the calculated accelerator pedal position. DIAGNOSTIC CONDITION:This diagnostic runs continuously when the ignition is on, but not during engine start-up. 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 accelerator pedal sensors with the diagnostic service tool. REPAIR VERIFICATION:1. Clear all DTCs.2. Test drive or operate the vehicle to meet the...
