New Ford Fiesta image by zimous from Fotolia.com. Check for missing fuel filler cap or integrity of the cap. This page explains how to get the codes without any special tools. If vehicle is not equipped with A/C, DTC P1460 can be ignored. The test fails if the PCM commands the fuel pump ON and B+ voltage is not detected on the FPM circuit. The test fails if: With the MFC output commanded on (grounded), excessive current draw is detected on the MFC circuit; or with the MFC circuit commanded off, voltage is not detected on the MFC circuit (the PCM expects to detect IGN START/RUN voltage coming through the medium speed FC relay coil to the MFC circuit). Damaged PCM The test fails when a response from the HO2S(s) being tested is not indicated. Low ambient temperature operation. Inductive Signature Chip Communication Error Indicates the PCM has lost communication with the Inductive Signature Chip. Cylinder Head Over Temperature Protection Active Indicates an engine overheat condition was detected by the cylinder head temperature (CHT) sensor. Damaged TP sensor Damaged muffler/tailpipe assembly Fuel Level Sensor Circuit Malfunction The PCM monitors the fuel level input (FLI) circuit for electrical failure. However, the system was troublesome, misunderstood by customers, and a rash of unpredictable failures led to the technology being quickly retired. When you see P3702 Ford Fiesta 7 engine fault code on your engine code reader this description will help you. You are not logged in. I have a fault code b1A55 on a ford fiesta . Open or short in Ignition START/RUN circuit FLI shorted to VPWR It is reasonably priced and will recover the purchase investment even if you use it just one time. Ford Fiesta and Fusion 2001 - 2002.

Plugged vacuum hoses A TP PID (TP V PID) reading less than 3.42% (0.17 volt) in key ON engine OFF, continuous memory or key ON engine running indicates a hard fault. Restricted EVAP canister Verify operation of charging system. Engine Fuel Temperature Sensor A Circuit Low Input (EFT) The comprehensive component monitor (CCM) monitors the EFT sensor circuit to the PCM for low voltage. It tells crash record output circuit . VCT solenoid valve stuck closed DTCs stored in a secondary module, which requested the MIL to be turned on. Note: DTC P0118 may also be reported when this DTC is set, either of these DTC's will activate the MIL light. P1170 ESO - … Cam timing improperly set Engine coolant temperature exceeds a calibrated value, typically 225F (107C). The test fails when the signal is shorted to power. Daewoo Musiro; Pontiac Firebird; Daihatsu Sportrak; B Codes: List of all Body codes. Damaged voltage regulator/generator All of the following sensors input data to the PCM for proper operation of the EEGR system: ECT, CPS, IAT, MAF, TP, MAP. But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off. Excessive fuel pressure. © 2021 Vehicle History Inc. All Rights Reserved. Damaged CCRM In this case, we turn on the radio and keep button 6 pressed for … Knock Sensor 1 Circuit Range/ Performance (Bank 1) The knock sensor detects vibrations upon increase and decrease in engine rpm. Diagnostic information will be set through SCP. When you manually edit your Windows Registry trying to take away the invalid ford fiesta fault code list keys you’re taking a authentic chance. Monitor IAT2 PID. Improper vacuum hose connection Camshaft advance mechanism binding (VCT unit) They are presented somewhat in order from most to least likely to be causing the code: Bad Spark Plugs– Spark plugs are one of the most common causes of P0304. Open coil driver circuit Excessive resistance in circuit. HO2S Sensor Circuit Slow Response (HO2S-11) The HEGO Monitor checks the HO2S Sensor frequency and amplitude. Intake Air Temperature 2 Circuit Low Input Indicates the sensor signal is less than Self-Test minimum. SIG RTN circuit open Damaged PCM. Malfunction EOT sensor or circuit (vehicles w/EOT sensor). Damaged Brake Switch Throttle plate below closed throttle position IMRC monitor signal circuit shorted to PWR GND or SIG RTN Idle Air Control (IAC) Overspeed Error This DTC is set when the PCM detects engine idle speed that is greater than the desired rpm. If no OSS DTCs are found check for correct PCM configuration. The EGR system is commanded ON at a fixed engine speed. Ignition LED Description; OFF: ... in other case trouble codes will appear fault code … Fuel Pump Primary Circuit Malfunction NOTE: For natural gas applications, the following description applies to the fuel shutoff valve (FSV) circuit. Coil driver circuit shorted to ground Open or shorted HFC circuit Plugged CV solenoid filter Drive vehicle and exercise throttle and TP sensor in all gears. Check RS PID while exercising shift lever in and out of reverse. The ECT sensor maximum is 4.6 volts or -50°C (-58°F). High fuel pressure Throttle Position (TP) Circuit Low Input The TP sensor circuit is monitored by the PCM for a low TP rotation angle (or voltage) input through the comprehensive component monitor (CCM). Shorted /open wiring. MAF sensor contamination Intercooler pump or relay failure The test fails when the fuel pressure falls below or exceeds a minimum/maximum calibrated value for a calibrated period of time. Camshaft advance mechanism binding (VCT unit) Damaged IAC valve Vacuum Leaks Misadjusted brake switch Locked warns us that the audio unit is blocked due to too many failed attempts. Crossed HO2S wiring at the 104-pin harness connectors (downstream). CMP circuit short to GND Damaged FTP sensor Fuel pump electrically open IAC circuit open If voltage were to fall below a calibrated limit and amount of time during testing, the test will fail. Check the circuit. Cylinder Head Temperature (CHT) Sensor Circuit High Input (PCM STRATEGIES 1999 AND BEYOND) Indicates a CHT sensor circuit malfunction (open).

Open FPDM PWR circuit Loose battery connection Inertia fuel shutoff (IFS) switch needs to be reset Monitor IAT on scan tool, look for sudden changes in reading when harness is wiggled or sensor is tapped. Crossed sensor wires. Improper harness connection. Drive the car for at least 10 miles for the ecu to learn, if there is a problem with your vehicle then the check engine light will come back on and you can analyze the fault code that the ECM throws. MAF sensor partially connected IAC circuit shorted to PWR Under normal closed loop fuel conditions, high efficiency catalysts have oxygen storage which makes the switching frequency of the downstream HO2S very slow and reduces the amplitude of those switches as compared to the upstream HO2S. Damaged EGRVR solenoid Misfire Monitor Disabled When the misfire monitor is disabled, usually due to the input signal generated by the camshaft position (CMP) sensor, by sensing the passage of teeth from the CMP wheel. Damaged FRP sensor. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. Open or shorted THTRC circuit Short to VPWR in FF sensor battery ground circuit Damaged knock sensor The electrical resistance of the solenoid windings is nominally 10 ohms. Blockages or kinks in EVAP canister tube or EVAP canister purge outlet tube (between fuel tank, EVAP canister purge valve and EVAP canister) Damaged TCS switch We unlock both Ford V & Ford M radio codes instantly, simply enter your ford serial number and your radio decode will display instantly. Failed EVAP system The test will fail when a malfunction is detected by PCM calculations indicating the EGR flow is less or greater than expected.

GLI circuit open or short EGR sensor Misfire Detection Monitor The misfire detection monitor is designed to monitor engine misfire and identify the specific cylinder in which the misfire has occurred. Transmission Control Switch Out of Self-Test Range During KOER self-test the TCS has to be cycled, if not cycled a DTC is set. Airbags are lifesavers when you are speeding and hit another car head-on or hit a stationary object. MAF RTN circuit open to PCM Stuck EGR valve. This condition will cause the boost from the supercharger to be bypassed to avoid potential engine damage. PNP/CPP circuit open in the SIGRTN Contaminated HO2S sensor.
