Abs Sensor Circuit Fault

Voltage is 02 Vac. When a wheel speed sensor WSS fails or theres a problem in the sensors wiring circuit it usually disables the ABS system and causes the ABS warning light to come on.

Diagnostic Trouble Codes DTCs.

Abs sensor circuit fault. Hard starting or no start. It may also be caused by a problem with the wiring and electrical connectors. Improper wiring or corroded damaged and otherwise faulty circuitry may be to blame for this circuit failure.

If the ABSPSM light stays on and the fault code still points to a faulty ABS sensor check the wire harness. Anti-Lock Brake System ABS Module Diagnostic Trouble Code DTC Index DTC Description Source Action B1342 ECU is Faulted ABS Module NOTE. Wiring incorrect Repair wheel sensor circuit as needed.

Different cars will have different ABS sensor configurations. Sensor signal failures caused by chafed or fractured circuit wiring sensor or connector corrosion or incorrect sensor fitment. There exists an open circuit.

The camshaft position sensor may have failed. Mass Air Flow MAF Sensor. Loss of engine power.

ABS warning light and other associated warning lights illumination. If the wire harness from the sensor to the ABS module is ok the ABS module could be the problem. The wheel speed sensor detects the magnetic field of the sensor ring as it passes the face of the active wheel speed sensor.

When i purchased Vcds and scanned the car with that it actually showed an Electrical Fault in the circuit. Bendix WS-24 Wheel Speed Sensors Wheel speed data is provided to the EC-60 controller from the WS-24 wheel speed sensor see Figure 2. The car originally had a Pressure sensor fault last year which showed up on my workshops Snap On scanner as an Implausible Signal.

Pulse wheel related problems arising from corroded or damaged teeth incorrect pulse ring fitment misalignment contamination from a build-up of ferrous material or an excessive air gap between the sensor and the pulse wheel. Rough running misfiring. If other DTCs are present REPAIR them before installing a new component.

Wheel speed sensor circuits and connectors are also prone to the atmosphere and possible electrical failures such as open or short circuits or high circuit resistances. Causes A code P0340 could mean one or more of the following has happened. The active wheel speed sensor generates a signal that is sent to the ABS module.

Loss of a wheel speed signal is a serious problem because the ABS module needs accurate input from all its sensors to determine whether or not a wheel is locking up. The abs system is like any other electrical system and is protected by a fuse that can blow if an electrical surge occurs or if the fuse ages. Over time the reluctor wheel may become dirty or damaged to the point where it can no longer provide a consistent reading or the magnetichall effect sensor may fail.

The PCM may have failed. If the fuse is blown and you replace it and it blows again there is a short circuit in the system which is usually the ABS. Multiple ABS circuit failure are sometimes solved at once by replacing a single sensor.

I therefore had the sensor g201 -front sensor changed earlier this year when the Turbo was replaced. The wheel speed sensor circuitry connects to the ABS module through 2 wires and a connector at each wheel speed sensor. When either of these components fail the ABS system will not function properly and will require service.

Check the AC voltage across pins 5 and 6 of the black X2 ECU connector while rotating the RF wheel 30 rpm. A wire or connector in the circuit could be groundedshortedbroken. Connector contains an ABS indicator lamp interlock X1-15 which shorts the ABS indicator lamp circuit X1-18 to ground if the connector is removed from the ECU.

Symptoms of ABS sensor related faults. Replacing the Porsche ABS wheel speed sensor is a straightforward procedure that you can perform yourself. Right Front Wheel Sensor Troubleshooting SID 002 MID SID FMI Problem Test Test Result Action 136 002 01 Incorrect sensor air gap 1.
