Disclaimer: This diagnostic code is part of the standard OBD2 system and can apply to Dodge Challenger models manufactured from 1996 to 2026. However, please note that the presence of this specific code depends on your vehicle's exact engine configuration, options, and production year.
Common Causes
Low, dirty, or burnt transmission fluid
Damaged, chafed, or broken wiring harness
Corroded or loose electrical connector
Symptoms to Watch For
- Check Engine Light is illuminated
- Transmission overheating warning
- Hard or harsh gear shifting
How to Diagnose
Common Solutions
Replace the Transmission Fluid Temperature Sensor: If diagnostic steps point to an internal fault within the sensor itself, replacement is necessary. Note that on many transmissions, the TFT sensor is integrated into the internal transmission wiring harness or even the valve body assembly, requiring a pan drop and fluid drain.
Repair or Replace Damaged Wiring Harness/Connectors: If the intermittent fault is traced to damaged, corroded, or chafed wiring in the external or internal transmission harness, or if the connector terminals are spread or corroded, the affected section of the harness or the entire harness may need to be repaired or replaced.
Clean Corroded Electrical Connectors: Thoroughly clean any corrosion found on the TFT sensor connector, the main transmission harness connectors, or the PCM/TCM connectors using electrical contact cleaner and a suitable brush. Apply dielectric grease to prevent future corrosion.
