if revs drop down below 850 and engine cuts out or struggles at 650rpm then valve has definitely failed. 8. Malfunction Indicator Lamp 1. Excessive resistance in circuit. It's easy! Source
Contaminated HO2S sensor. P0605 Error Description PCM read only memory (ROM) error Indicates the PCM ROM has been corupted. Damaged harness Damaged sensor Damaged harness connector Damaged PCM Engine should be at operating temperature before running self-test. P0457 Error Description EVAP Control System Leak Detected (Fuel Filler Cap Loose/Off) A fuel tank pressure change greater than a minus (-) 7 inches of H 2 0 in 30 seconds
Wird geladen... The system failure occurs when a fuel vapor leak from an opening as small as 1.016 mm (0.04 inch) is detected by the EVAP running loss monitor test. Severely restricted fuel filter. On most vehicle applications the malfunction indicator lamp (MIL) will be triggered when this DTC is set.
FLI PID at 25% fill (with non matching fuel gauge) and FLI V PID less than 0.90 volts [for FLI PID at 75% fill (with non matching fuel gauge) and FLI P0186 Error Description Engine Fuel Temperature Sensor B Circuit Range/Performance (EFT) See DTC P0181. Contamination internal to FTP sensor connector Damaged PCM FTP circuit shorted to GND or SIG RTN Damaged FTP sensor FTP V PID reading less than 0.22 volt with key ON and Ford Obd1 Trouble Codes P0131 Error Description HO2S Sensor Circuit Out of Range Low Voltage (HO2S-11) The HO2S sensor is monitored for a negative voltage known as characteristic shift downward (CSD).
P0721 Error Description Noise interference on Output Shaft Speed sensor signal The output shaft speed sensor signal is very sensitive to noise. switch on all electrics - headlights, heated screen, heater blower etc 6. During KOEO and KOER self-test, the fuel pump output command will be cycled ON and OFF. Calibrated timer to set DTC P0116 has expired.
Using Check Engine/ MIL Exc DI 7.3L Turbo Diesel, Merkur (2.9L), Villager & 85–88 2.3L Engine The MIL lamp is intended to alert the driver of certain malfunctions in the engine Ford F150 Check Engine Light Codes Continuous DTCs should now be erased. Blockage of heat exchangers Low fluid level Fluid leakage Intercooler pump or relay failure Crossed intercooler coolant lines Monitor IAT2 PID. The test fails when current draw exceeds a calibrated limit and/or an open or short is detected.
FRP signal open (gasoline only) Low fuel pressure (NG only) Damaged FRP sensor. If vehicle speed data is lost, check the source of where the vehicle speed input originates from: VSS, TCSS, ABS, GEM or CTM. Ford Focus Error Codes On Panel So please read our Disclaimer and when you're ready jump in!

Damaged PCM. this contact form Open or short in harness. and MORE!! NOTICE: The information contained on this site is presented for information only. Ford Engine Codes List
However there are external items that can cause this DTC. Monitor VSS PID while driving vehicle, check for intermittent vehicle speed indication. Damaged harness Damaged sensor Damaged harness connector Damaged PCM Monitor IAT on scan tool, look for sudden changes in reading when harness is wiggled or sensor is tapped. http://jamisonsoftware.com/ford-focus/ford-focus-error-codes-dtc-9318.php As catalyst efficiency deteriorates, its ability to store oxygen declines and the downstream HO2S signal begins to switch more rapidly with increase amplitude, approaching the switching rate and amplitude of the
May cause Lack/Loss of Power or Surge customer concern. Ford Flash Codes fuel system test or prime procedure). P0121 Error Description Throttle Position (TP) Circuit Performance Problem The TP sensor circuit is monitored by the PCM for a non closed throttle position at idle.
EGR Vacuum Regulator circuit malfunction P1409? FRP signal shorted to SIG RTN or PWR GND. P0456 Error Description EVAP Control System Leak Detected (Very Small Leak) The PCM monitors the complete EVAP control system for the presence of a very small fuel vapor leak. Ford Focus Fault Code Dtc D900 We can provide information on component location, specifications, circuit color/location and more.
Open or short in FF sensor VPWR circuit Open in battery ground to FF sensor circuit Open in FF sensor signal circuit Short to ground in FF sensor signal circuit Fuel The test fails when the inferred pressure is higher than a maximum calibrated value. For lean and rich DTCs: Fuel system Excessive fuel pressure. http://jamisonsoftware.com/ford-focus/ford-focus-dashboard-error-codes.php Suspect this is the idle control valve, as had diagnostics in the past which have shown nothing.
Short to GND in VSS harness circuit. P0340 Error Description Camshaft Position (CMP) Sensor Circuit Malfunction The test fails when the PCM can no longer detect the signal from the CMP sensor. Open or shorted low fuel pump (LFP) circuit Open VPWR to low speed fuel pump relay Damaged low speed fuel pump relay Damaged PCM An open circuit or short to ground The Fuel, Heated Oxygen Sensor, Catalyst and Misfire monitors have not completed.
If during key ON engine running the air flow (or voltage) changes below a minimum calibrated limit, the test fails. Unlatch push button on Super Star II Tester as soon as first diagnostic trouble code is received. 3. VID data corrupted by the scan tool during VID reprogramming Using the scan tool, reprogram the VID block. However, as previously stated, a DTC is represented by a two digit number, such as 2–3.
The test fails if: With the FP output commanded ON (grounded), excessive current draw is detected on the FP circuit; or with the FP output commanded OFF, voltage is not detected This noise distorts the input to the PCM. Veröffentlicht am 04.09.2014This kit is available here http://www.ukprodiagnostics.co.uk/pag... During KOEO self-test, the PCM will command the fuel pump ON so this test can be performed.
