Left Front Tire Pressure Sensor/Transmitter Signal Jammed

SYMPTOM
LEFT FRONT TIRE PRESSURE SENSOR/TRANSMITTER SIGNAL JAMMED

WHEN MONITORED
With the ignition on, the Tire Pressure Monitor (TPM) monitors the tire pressure sensor/transmitters approximately once a minute (60 - 68 seconds) when the vehicle speed is above 33 km/h (20 mph).

SET CONDITION
If the Tire Pressure Monitor (TPM) module receives an undetectable frequency transmission from the left front tire pressure sensor/transmitter, the DTC will be set.

- Outside Radio Frequency Interference

DIAGNOSTIC TEST

1. Check For Current DTC

Turn the ignition on.





With the DRBIII, read the TPM DTCs.

Is this DTC preset?

Yes >> For complete diagnosis of this DTC, refer to TIRE PRESSURE SENSOR/TRANSMITTER SIGNAL JAMMED.
