PACCAR PX-8 CM2150 (2007-09) Fault Code: 242 PID: 84 SPN: 84 FMI: 10 Wheel-Based Vehicle Speed Sensor Circuit Tampering Has Been Detected – Abnormal Rate of Change. Signal indicates an intermittent connection or VSS tampering.
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.
Verify that the feature settings for the vehicle speed sensor anti-tampering (Fault Code 242), application type and automatic transmission are set correctly. If any of these are set incorrectly for the specific vehicle and application, Fault Code 242 could occur erroneously.
Driving techniques such as driving for extended periods of time in lower gears can log Fault Code 242. Fault Code 242 can be logged if the driver attempts to defeat the road speed governor by repeatedly cycling the keyswitch.
Once the speed signal has been restored the fault code will go inactive once the keyswitch is on for 30 seconds and the ECM senses zero vehicle and engine speed.
Possible repairs:
1)Repair or replace the OEM harness.
2)Replace the ECM.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 241 PID: 84 SPN: 84 FMI: 2 Wheel-Based Vehicle Speed – Data Erratic, Intermittent, or Incorrect. The ECM lost the vehicle speed signal.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 239 PID: SID 232 SPN: 3511 FMI: 3 Sensor Supply 3 Circuit – Voltage Above Normal or Shorted to High Source. High voltage detected at sensor supply number 3 circuit.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 238 PID: SID 232 SPN: 3511 FMI: 4 Sensor Supply 3 Circuit – Voltage Below Normal or Shorted to Low Source. Low voltage detected on the +5 volt sensor supply circuit to the engine speed sensor.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 234 PID: 190 SPN: 190 FMI: 0 Engine Crankshaft Speed/Position – Data Valid but Above Normal Operational Range – Most Severe Level. Engine speed signal indicates engine speed above engine protection limit.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 222 PID: 108 SPN: 108 FMI: 4 Barometric Pressure Sensor Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at barometric pressure circuit.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 221 PID: 108 SPN: 108 FMI: 3 Barometric Pressure Sensor Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at barometric pressure circuit.
