U142A RAM Code - Implausible PRNDL Signal Received
Quick Answer
There are two qualifying states that the Occupant Restraint Control (ORC) Module uses to modify a Active Headrest (AHR) deployment. Common causes include Faulty Powertrain Control Module (PCM), Powertrain Control Module (PCM) harness is open or shorted, Powertrain Control Module (PCM) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Frequently Asked Questions about U142A RAM Code
1. What does OBDII code U142A mean on a RAM vehicle?
U142A indicates that the vehicle's Powertrain Control Module (PCM) has received an implausible signal from the PRNDL (Park, Reverse, Neutral, Drive, Low) position sensor.
2. What are common symptoms of the U142A code in a RAM vehicle?
Common symptoms include incorrect gear selection display, transmission not shifting properly, or the vehicle being stuck in a specific gear.
3. What causes the U142A code to appear?
This code can be triggered by a faulty PRNDL position sensor, damaged wiring or connectors, a misaligned shift linkage, or a malfunction in the Transmission Control Module (TCM).
4. Can I drive my RAM vehicle with a U142A code?
Driving with this code is not recommended, as improper gear indication or shifting issues can lead to unsafe driving conditions or further damage to the transmission.
5. How is the U142A code diagnosed?
A technician will use a scan tool to check for related codes, inspect the PRNDL sensor and its wiring, and verify the gear position signals sent to the PCM.
6. How do I fix the U142A code on my RAM vehicle?
Repairs may involve replacing the PRNDL position sensor, repairing damaged wiring or connectors, recalibrating the shift linkage, or updating the TCM software.
7. What tools are needed to diagnose and repair the U142A code?
A diagnostic scan tool, multimeter, and possibly a repair manual for your specific RAM model are required for proper diagnosis and repair.
8. How much does it cost to fix the U142A code?
Repair costs can range from $100 to $500 or more, depending on whether the issue is a simple wiring repair or requires replacing the PRNDL sensor or TCM.
9. Can a low battery cause the U142A code?
Yes, a weak or failing battery can cause communication errors between modules, potentially triggering the U142A code.
10. Will clearing the code with a scan tool fix the U142A issue?
Clearing the code may temporarily remove it, but the underlying issue must be resolved to prevent the code from returning.
