C0036Left Rear Tone Wheel
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- Covers the left rear tone wheel (reluctor or encoder ring) read by the left rear wheel speed sensor, the rear-axle counterpart of C0030 and C0033. It is a signal-plausibility code set when the module sees an erratic, noisy or intermittent rear speed signal consistent with a damaged, contaminated or loose tone ring rather than a sensor circuit failure. Ford documents C0036 with C0037 and C003A on 2021 Bronco and Ranger vehicles with an illuminated ABS warning. A fault disables ABS, traction and stability control and lights the ABS warning lamp while base braking remains; on vehicles that use the rear sensors for electronic brake-force distribution that function is affected too.
