C212A on Jeep
Manufacturer-Specific TPMS Transmitter/Sensor Fault
C212A on Jeep vehicles indicates manufacturer-specific tpms transmitter/sensor fault. Au7o has documented this code across 1 Jeep model — most commonly on Gladiator. C212A is an obscure manufacturer-specific chassis code within the Tire Pressure Monitoring System code family. It generally indicates a transmitter (wheel sensor) or signal-reception fault detected by the TPMS ECU. Because the exact definition is maker-specific and could not be confirmed against a public standard, it should be interpreted conservatively as a TPMS sensor/transmitter circuit fault. The TPMS warning light usually comes on and a tire pressure value may not be reported. Typical repair costs on Jeep range from $300 to $1,500, depending on the specific model and root cause.
Common Causes of C212A
- •Weak or dead TPMS sensor battery
- •Faulty or missing tire pressure transmitter
- •Sensor ID not registered to the ECU
- •Receiver/antenna or wiring fault
- •RF interference
- •TPMS module fault

- Electronic Locker (E-Locker) Actuator Failure2020-2025
The electronic locking rear differential (standard on Rubicon, optional on others) develops actuator failures that prevent the e-locker from engaging or disengaging. The electric motor actuator that engages the locking ring can fail from moisture intrusion, corrosion, or internal motor burnout — particularly after water crossings or heavy off-road use. When stuck in the locked position, the differential causes binding and tire chirping on pavement. When stuck disengaged, it fails to provide traction when needed.
