C0040 CHEVROLET code

Code C0040 indicates the ABS module has determined a problem with the right front wheel speed sensor or its circuit.

What could cause a trouble code for one of the wheel speed sensors?

The most common causes behind this engine code are: Faulty Left Wheel Speed Sensor. Left Front Wheel Speed Sensor harness is open or shorted. Left Front Wheel Speed Sensor circuit has a poor electrical connection.

What is wheel speed sensor circuit?

Zitat von Youtube: So we're talking about a wheel speed sensor what does that have to do with ABS at all ABS stands for anti-lock brake system and it's there to help you control the vehicle during slippery situations.

What is code C0055?

Code C0055 stands for Rear Wheel Speed Sensor Circuit. The anti-lock brake system (ABS) prevents wheel lockup during emergency braking. This is accomplished by modulating brake pressure to the appropriate wheels. In essence, the ABS system “pumps” the brakes in a panic stop.

What is code C0035?

Diagnostic trouble code (DTC) C0035 stands for “Left Front Wheel Speed Sensor.” Wheel speed input is typically used for vehicle dynamics purposes such as anti-lock brakes, stability control, traction control, etc.

Where is the wheel speed sensor?

A wheel speed sensor, also called an “ABS sensor,” is part of the Anti-lock Brake System (ABS). It is located on the tires (near the brake rotors for the front tires and in the rear end housing for the rear tires).

How do you test a wheel speed sensor?

Set a multimeter to measure resistance (ohms). Place each probe of the multimeter on each pin inside the connector. Connect it to the end of the wire that comes from the sensor. Note the ohm reading on the gauge.

What happens when wheel speed sensor fails?

A failing wheel speed sensor will turn off your vehicle’s traction control, stability control, or any other driver assist feature. Sometimes, a damaged wire could also prevent the sensor from sending data to the control module.

Can wheel speed sensor affect transmission?

As a bad wheel speed sensor sends unrealistic wheel speed values, the transmission cannot decide the right gear for the vehicle. It can cause the engine to stall or the transmission to lock up in the first gear only or cause the transmission to shift gears with strong jerks.
