This condition will cause the boost from the supercharger to be bypassed to avoid potential engine damage. Powertrain Control Module KAM Test Error Indicates the PCM has experienced an internal memory fault. Damaged PCM Ford Fiesta Owner's Manual 346 pages. Powertrain DTC's Available in Another Module Vehicles using a secondary Engine Control Module can request that the Powertrain Control Module illuminate the Check Engine Light when a failure occurs which affect emission. Plugged or damaged EGR tube The red cog with a red exclamation mark warning light signifies a fault with the powertrain. Damaged PCM Damaged PCM. GLI circuit open or short Engine Fuel Temperature Sensor A Circuit High Input (EFT) The comprehensive component monitor (CCM) monitors the EFT sensor circuit to the PCM for high voltage. Fuel Rail Pressure Sensor Circuit High Input (FRP) The comprehensive component monitor (CCM) monitors the FRP sensor circuit to the PCM for high voltage. Pump motor shorted Fuel Rail Pressure Sensor Circuit Malfunction (FRP) The comprehensive component monitor (CCM) monitors the FRP sensor to the PCM for VREF voltage. If this is the case the Misfire Detection Monitor will indicate the EGR port to check for possible blockage. Damaged FRP sensor. CHT V PID reading greater than 4.6 volts with key ON and engine OFF or during any engine operating mode indicates a hard fault. Open VPWR circuit to fuel pump relay ACP circuit short to GND or SIGRTN Engine Fuel Temperature Sensor A Circuit Range/ Performance (EFT) The comprehensive component monitor (CCM) monitors the EFT Temperature for acceptable operating temperature. Cylinder Head Temperature (CHT) Sensor Circuit Out of Self-Test Range Indicates the CHT sensor is out of Self-Test range. Monitor IAT on scan tool, look for sudden changes in reading when harness is wiggled or sensor is tapped. Damaged IFS switch Knock Sensor 2 Circuit Malfunction (Bank 2) See DTC P0331. HO2S Sensor Circuit Malfunction (HO2S-125) See DTC P0135. ACP circuit short to VREF Air Conditioning Pressure Sensor (ACP) Insufficient Pressure Change Each time the A/C clutch engages, the PCM is looking for a pressure change in the refrigerant. The warning light that comes on the display when your front fog lights … Open VPWR circuit to low speed FC relay Damaged EGRVR solenoid Reprogram or update calibration. Vehicle Speed Sensor (VSS) Malfunction Indicates the powertrain control module (PCM) detected an error in the vehicle speed information. If the fault is no longer detected, the PDM will return to sending an "all OK" (50% duty cycle) message to the PCM. Damaged sensor TP sensor not seated properly There are three dashboard light colors on most dashboards: yellow, red, and orange (and, occasionally, blue or green). Engine operating in high rpm range, due to improper gear selection. Disconnect SCB solenoid. Damaged fuel pump relay Damaged PCM Improper harness connection Improper harness connection Cylinder Head Over Temperature Sensed Indicates an engine overheat condition was sensed by the cylinder head temperature sensor. PSP sensor signal circuit open or shorted Sounds to me as the alternator could be starting to fail, I'm afraid. Random Misfire The random misfire DTC indicates multiple cylinders are misfiring or the PCM cannot identify which cylinder is misfiring. Excessive fuel pressure One or more EGR passages may be blocked or partially blocked. The test fails when the fuel pressure falls below or exceeds a minimum/maximum calibrated value for a calibrated period of time. Incorrect VID configuration parameters Insufficient input from Output Shaft Speed sensor The output shaft speed sensor inputs a signal to the PCM, based on the speed of the output shaft of the transmission. Open VPWR circuit to WAC relay Look for signs of water or icing in hose Damaged PCM Damaged PCM EVAP canister purge valve circuit open The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum. Please also check out the statistics and reliability analysis of the 2014 Ford Fiesta based on all problems reported for the 2014 Fiesta. The PCM monitors the fuel pump monitor (FPM) circuit from the fuel pump driver module (FPDM). The test fails if: the PCM detects voltage either too high or too low when compared to the expected voltage range on the (HCF) primary circuit. The powertrain is usually referring to your car's engine system. SIG RTN circuit open to TP sensor A/C sensor damaged Throttle plate below closed throttle position Damaged MAF sensor The FPDM will send a message to the PCM through the FPM circuit, indicating that this failure has been detected. The AIR circuit is normally held high through the AIR bypass solenoid and SSR when the output driver is off. Low battery voltage. Connect test lamp to SCB solenoid harness connector. FRP signal shorted to SIG RTN or PWR GND. Damaged PCM MAF sensor. VREF shorted to VPWR Compare HO2S upstream and downstream switch rate and amplitude. Damaged medium speed FC relay Very high engine rpm for extended period of time. Ford Fiesta ST » Forums » Fiesta ST 2005-09 » Mk6 Fiesta ST Technical Talk » Powertrain Warning Lamp Register User Forum List Calendar Active Topics Search FAQ Using the scan tool, reprogram the VID block. While accessing the MAF V PID on the scan tool, lightly tap on the MAF sensor or wiggle the MAF sensor connector and harness. The DTC does not need to be cleared from the PCM except to pass an inspection/maintenance test. The test fails when the EGRVR circuit voltage is either too high or too low when compared to the expected voltage range. Insufficient Coolant Temperature For Closed Loop Fuel Control Indicates the ECT or CHT sensor has not achieved the required temperature level to enter closed loop operating conditions within a specified amount of time after starting engine. Damage drive mechanism for VSS or TCSS. If during testing the frequency and amplitude were to fall below a calibrated limit, the test will fail. Crossed intercooler coolant lines Likewise, if during key ON engine running, an air flow voltage signal is not within 0.46 volt to 2.44 volts, the test fails. Open in battery ground to FF sensor circuit Fuel Pump Control Out Of Range See DTC P1235. MAF RTN circuit open to PCM how to reset the #powertrain waning light. Fuel Pump Secondary Circuit Malfunction Note: For LS6/LS8, the FPDM functions are incorporated in the rear electronics module (REM). The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified purge duty cycle by PCM command. Vehicle towed with engine running Indicates that the FPDM has detected an invalid or missing FP circuit signal from the PCM.
