Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM. This fault code becomes active when the aftertreatment diesel oxidation catalyst inlet and aftertreatment diesel particulate filter inlet temperature sensors do not detect the presence of a catalyst in the aftertreatment system. Possible causes: 1)Tampering with the catalyst system2)Removing the catalyst system from the vehicle3)A damaged catalyst. Possible repairs: 1)Install the proper diesel oxidation catalyst for the application. PACCAR PX-6 CM2150 (2007-09) Fault Code: 1663 PID: SPN:...
PACCAR PX-6 CM2150 (2007-09) Fault Code: 1665 PID: SPN: 3241 FMI: 4 Aftertreatment Exhaust Gas Temperature 1 Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the catalyst inlet sensor circuit.

Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM. The aftertreatment diesel oxidation catalyst inlet temperature sensor shares return wires in the OEM harness with other sensors. A shorted return wire can cause multiple fault codes to be active. Possible causes: 1)Signal shorted to ground in the harness2)Signal shorted to return or ground in the sensor. Possible repairs: 1)Replace the aftertreatment diesel oxidation catalyst inlet temperature sensor.2)The removal and installation of the connector may correct the...
PACCAR PX-6 CM2150 (2007-09) Fault Code: 1666 PID: SPN: 3241 FMI: 3 Aftertreatment Exhaust Gas Temperature 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at the catalyst inlet temperature sensor circuit.

Verify the ECM calibration is correct. Check the calibration revision history found on QuickServe™ Online for applicable fixes to the calibration stored in the ECM. If necessary, calibrate the ECM. Reference the following procedure in the corresponding Troubleshooting and Repair Manual for the engine being serviced. The aftertreatment sensors share a common ground wire with the coolant level sensor. Fault codes or problems related to the coolant level sensor and its ground circuit could potentially cause this fault. Possible causes: 1)Coolant level sensor and/or coolant level sensor ground circuit fault codes or related problems2)Stuck in-range aftertreatment diesel oxidation catalyst inlet...
