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. Possible causes: 1)Open return circuit in the harness, connectors, or sensor2)Open signal circuit or shorted to a voltage source. Possible repairs: 1)Refer to the OEM service manual for additional specifications.2)Replace the OEM temperature sensor.3)Repair or replace the OEM harness.4)Replace the ECM. PACCAR PX-8 CM2150 (2007-09) Fault Code: 292 PID: 441 SPN: 441 FMI: 14 Auxiliary Temperature Sensor Input 1 – Special Instructions. PACCAR PX-8 CM2150 (2007-09) Fault...

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. Possible causes: 1)Signal shorted to ground in the harness2)Signal shorted to return or ground in the sensor. Possible repairs: 1)Replace the OEM temperature sensor.2)Repair or replace the OEM harness.3)Replace the ECM. PACCAR PX-8 CM2150 (2007-09) Fault Code: 293 PID: 441 SPN: 441 FMI: 3 Auxiliary Temperature Sensor Input 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage or open circuit detected at...

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. At key-on, before the engine starts, the sensor readings for intake manifold pressure, exhaust gas pressure (if equipped), and engine oil pressure (if equipped) are compared with the barometric pressure. This fault code occurs if the barometric pressure sensor reading is different from the other three. This check is only done once after the keyswitch is turned on. Possible causes: 1)Stuck in-range barometric pressure sensor reading.2)High resistance...

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. This fault code is activated when the pressure input from the OEM sensor exceeds the engine protection limit defined by the OEM. An engine power derate is possible depending on the OEM application. Possible repairs: 1)Replace the OEM harness.2)If necessary, recalibrate the ECM. PACCAR PX-8 CM2150 (2007-09) Fault Code: 295 PID: 108 SPN: 108 FMI: 2 Barometric Pressure – Data Erratic, Intermittent, or Incorrect. The ambient air pressure sensor is reading an...

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, calibrate the ECM. Possible causes: 1)Plugged or leaking EGR differential flow ports2)A malfunctioning EGR valve3)A stuck open turbocharger control valve4)A low reading from the EGR differential pressure sensor5)A low reading for the EGR valve position sensor6)High exhaust temperatures7)Low coolant level8)High coolant temperature9)An incorrect coolant/water mixture10)A stuck closed variable geometry turbocharger11)A fouled EGR cooler. Note: This fault code will most likely not be active with no load in the shop. The...
