Are you seeing the ‘Check Engine’ light in your Chevrolet vehicle? If so, you may have the Chevrolet C0035 18 Code. This code is generated when the Left Front Wheel Speed Sensor Circuit Signal Amplitude is less than the minimum value. It is important to understand the causes and solutions for this code to ensure the safety of your vehicle. In this article, we will discuss the causes, symptoms, and solutions for this code. We will also look at the different types of Failure Type Circuit Current Below Threshold and how to solve it. With this knowledge, you can better understand how to maintain your Chevrolet vehicle and keep it running safely.
Causes and Solutions for C0035 18 Code
| Causes | Solutions |
|---|---|
| Short to ground on wheel speed 12 V reference or signal circuit | Diagnose and repair the wiring and connectors on the wheel speed sensor circuit |
| Short to voltage, or an open on 12 V reference or the signal circuit | Replace the wheel speed sensor, wheel speed sensor circuit wiring, or the wheel speed sensor connector |
| Erratic signal output of the wheel speed sensor detected 3 times in 200 milliseconds | Replace the wheel speed sensor, wheel speed sensor circuit wiring, or the wheel speed sensor connector |
| EBCM detects a change in wheel speed that exceeds 20 km/h in two 10 millisecond wheel speed samples 3 times in 200 milliseconds | Diagnose and repair the wiring and connectors on the wheel speed sensor circuit |
Short to Ground on Wheel Speed 12 V Reference or Signal Circuit
A short to ground on the wheel speed reference or signal circuit is one of the causes for the Chevrolet C0035 18 Code. This happens when the voltage in the wheel speed reference or signal circuit drops below a certain threshold. To diagnose and repair this issue, you will need to check the wiring and connectors on the wheel speed sensor circuit.
Short to Voltage, or an Open on 12 V Reference or the Signal Circuit
Another cause of the Chevrolet C0035 18 Code is when there is a short to voltage, or an open on the 12 V reference or the signal circuit. In this case, you will need to replace the wheel speed sensor, wheel speed sensor circuit wiring, or the wheel speed sensor connector.
Erratic Signal Output of the Wheel Speed Sensor Detected 3 Times in 200 Milliseconds
If the erratic signal output of the wheel speed sensor is detected 3 times in 200 milliseconds, then you will need to replace the wheel speed sensor, wheel speed sensor circuit wiring, or the wheel speed sensor connector. This can be caused by a faulty wheel speed sensor or faulty wiring or connectors.
EBCM Detects a Change in Wheel Speed that Exceeds 20 km/h in Two 10 Millisecond Wheel Speed Samples 3 Times in 200 Milliseconds
The last cause of the Chevrolet C0035 18 Code is when the EBCM detects a change in wheel speed that exceeds 20 km/h in two 10 millisecond wheel speed samples 3 times in 200 milliseconds. In this case, you will need to diagnose and repair the wiring and connectors on the wheel speed sensor circuit.
Conclusion
The Chevrolet C0035 18 Code is generated when the Left Front Wheel Speed Sensor Circuit Signal Amplitude is less than the minimum value. In this article, we discussed the causes, symptoms, and solutions for this code. We also looked at the different types of Failure Type Circuit Current Below Threshold and how to solve it. With this knowledge, you can better understand how to maintain your Chevrolet vehicle and keep it running safely.
