This summary uses the existing diagnostic information shown in full below.
The car's computer thinks the right front wheel is spinning at a speed that doesn't make sense, like if it thinks the wheel is going faster or slower than it really is.
The wheel speed sensor sends information about how fast the wheel is spinning to the car's computer. If the signal doesn't match expected values, the computer flags it as implausible.
The C1236 code indicates that the signal from the right front wheel speed sensor is not consistent with the expected values. This could be due to a sensor malfunction, wiring issue, or a problem with the wheel itself.

Sensor Issue
• Have the vehicle inspected by a professional.
• Avoid driving in conditions where ABS is critical until repaired.
Check with your vehicle manufacturer for warranty coverage on ABS components.
This code has been associated with sensor failures and wiring issues in various vehicle models.
Moderate – It is important to address this issue to ensure proper ABS and traction control function.
Driving with a malfunctioning ABS system can increase stopping distances and affect vehicle control in emergency situations.
• Vehicle stationary
• Ignition on
The right front wheel speed sensor is located near the wheel hub assembly of the right front wheel.
Q: Can I drive with a C1236 code?
A: It's possible to drive, but it's not recommended as the ABS system may not function properly.
Q: How do I reset the ABS light?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
