If you’re here, you might be dealing with the GM diagnostic trouble code C0242 00, which is often associated with issues in the anti-lock braking system (ABS) of Chevrolet vehicles. This can definitely be a challenging problem to tackle, but let’s break it down and see if we can figure it out together.
What Does C0242 00 Mean?
This specific DTC indicates a fault with the wheel speed sensor or the ABS control module. When this code triggers, your vehicle may exhibit symptoms such as:
ABS warning light on your dashboard
Erratic braking behavior
Potential loss of ABS functionality during hard braking
Common Causes
Here are some common culprits that can lead to C0242 00:
Faulty wheel speed sensor: This is often the first suspect. If it’s failing or has a poor connection, it can trigger the DTC.
Wiring issues: Damaged or frayed wires can lead to improper readings from the wheel speed sensor.
Faulty ABS module: The module itself could have faults preventing it from processing information correctly.
Troubleshooting Steps
To resolve the issue, you can follow these steps:
Check the Codes: Use an OBD-II scanner to confirm the presence of C0242 00 and any other related codes.
Inspect the Wheel Speed Sensors: Check for any visible damage, loose connectors, or debris around the sensors.
Examine the Wiring: Look at the wiring leading to the sensors for any signs of wear and tear.
Test the ABS module: If the sensors and wires look good, you may need to conduct further testing on the ABS control module to ensure it is functioning correctly.

I’ve been dealing with the C0242 00 code recently. It indicates an issue with the rear wheel speed sensor. Commonly, this code is triggered by a faulty sensor or damaged wiring. It can really impact stability control, so it’s essential to address it.
That’s interesting! I didn’t realize the sensor could affect stability control so much. Has anyone had success fixing this without replacing the sensor?
The C0242 00 can definitely bring your vehicle’s performance down. Besides sensor issues, it might also involve problems with the ABS module. I think it’s worth checking both areas.
I paid around $500 for a garage to handle it. A bit steep, but the peace of mind was worth it. Sometimes DIY isn’t always the best choice if you’re unsure.
I’ve had this code pop up before! C0242 00 usually indicates a problem with the ABS system. Start by inspecting the vehicle speed sensor and the ABS wheel speed sensors. Good luck!
