P0883 RAM Code - TCM Power Input Signal High
Quick Answer
The Transmission Control Output circuit is used to supply power to the Transmission Solenoid/TRS Assembly and to the Powertrain Control Module (PCM) when in normal operating mode. Common causes include Faulty Transmission Control Relay, Faulty Transmission Solenoid Assembly, Faulty Transmission Control Module (TCM). 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.

Code P0883 RAM Description
After a PCM reset, (ignition switch turned to the run position, or after cranking the engine) the Transmission Control System verifies that the Transmission Output circuit is open by checking for voltage on the Transmission Output circuits before the Transmission Control System requests for the circuit to be powered up. If voltage is detected on the Transmission Output circuits before the request is sent, the DTC will set.
This DTC is set if the PCM senses greater than 3.0 volts on the Transmission Control Relay Output circuits prior to a request from the PCM to energize the Transmission Output circuits.
What are the Possible Causes of the DTC P0883 RAM?
- Faulty Transmission Control Relay
- Faulty Transmission Solenoid Assembly
- Faulty Transmission Control Module (TCM)
- Transmission Control Module harness is open or shorted
- Transmission Control Module circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How to Fix the DTC P0883 RAM?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0883 RAM code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0883 RAM Code
1. What does OBDII code P0883 mean for a RAM vehicle?
P0883 indicates that the transmission control module (TCM) has detected a higher-than-expected voltage at its power input circuit.
2. What are the common symptoms of code P0883 in a RAM?
Symptoms may include harsh or erratic shifting, the transmission stuck in limp mode, the check engine light illuminated, and reduced fuel efficiency.
3. What causes the P0883 code in a RAM?
Common causes include a faulty TCM, damaged wiring or connectors in the TCM power input circuit, a failing transmission relay, or electrical system issues like a bad battery or alternator.
4. Can a bad TCM cause the P0883 code?
Yes, a faulty TCM can cause the P0883 code if it incorrectly reads the power input voltage or fails to operate properly.
5. How do I troubleshoot code P0883 in my RAM?
Start by inspecting the TCM power input circuit wiring and connectors for damage or corrosion, testing the transmission relay, and checking the battery and alternator output voltage.
6. Is it safe to drive a RAM with the P0883 code?
Driving with this code is not recommended, as it can lead to transmission issues like being stuck in limp mode, which may cause further damage.
7. How can I fix the P0883 code on my RAM?
Repairs may include replacing damaged wiring or connectors, replacing the transmission relay, repairing or replacing the TCM, or addressing electrical system issues.
8. Can a low battery cause the P0883 code in a RAM?
Yes, a low or failing battery can cause voltage irregularities, potentially triggering the P0883 code.
9. How much does it cost to fix code P0883 on a RAM?
Repair costs depend on the issue, ranging from $50 for a simple wiring repair to $1,000+ if the TCM needs replacement.
10. Can clearing the P0883 code solve the problem?
Clearing the code without addressing the underlying issue will not fix the problem, and the code is likely to return.
