This code doesn't pinpoint the *exact* problem, but it points to issues within the circuit connecting the output speed sensor to the PCM. Possible causes include:
* Faulty Output Speed Sensor: This is the most likely culprit. The sensor itself might be malfunctioning due to wear, damage, or internal failure.
* Wiring Problems: A broken, shorted, or corroded wire in the circuit leading to or from the sensor can cause this code. This might involve connectors as well.
* PCM Problem (less likely): While less common, a malfunctioning PCM can also trigger this code. This is usually diagnosed after other possibilities are ruled out.
* Transmission Issues (possible, but needs further diagnosis): Sometimes, internal transmission problems can indirectly cause this code. However, it's usually a symptom of one of the other problems listed above.
What to do:
1. Have the code properly diagnosed: While you can get a general idea from the code, a professional mechanic can use a scan tool to get more detailed information and pinpoint the problem more accurately. They can also perform tests to verify sensor operation and check the wiring harness.
2. Check the sensor: A mechanic will likely inspect the output speed sensor for any physical damage or corrosion. They may even test its resistance and voltage to confirm its functionality.
3. Inspect the wiring: The wiring harness connecting the sensor to the PCM should be visually inspected for any damage, breaks, or corrosion. They will likely check the connectors as well.
4. Consider a transmission fluid change: While not directly related to the code, low or contaminated transmission fluid can contribute to transmission problems. A fluid change is relatively inexpensive and might resolve underlying issues that are causing the sensor to malfunction.
Do not attempt to repair this yourself unless you have significant automotive experience. Improper repairs can lead to further damage or injury. It's best to take your Dodge to a qualified mechanic for diagnosis and repair.
