The OBD2 code P0887 refers to a problem in the Transmission Control Module (TCM) power relay control circuit, specifically indicating a high voltage issue. This code is part of the diagnostic trouble codes that vehicles use to communicate faults within various systems.
What Does the P0887 Code Mean?
The P0887 code means that the TCM is not receiving the proper voltage from the power relay, which can lead to transmission problems. When this occurs, the engine control module (PCM) is notified to set this code as a warning.
What Causes the P0887 Code?
Several factors can trigger the P0887 code, including:
- Transmission Control Module (TCM) failure
- Transmission Control Module (TCM) relay failure
- Wiring issues or short circuits
What Are the Symptoms of the P0887 Code?
Common symptoms associated with the P0887 code include:
- Transmission may not shift properly
- Increased fuel consumption
How Serious Is the P0887 Code?
The P0887 code is classified as a moderate severity issue. While it may not immediately threaten the vehicle’s safety, it is advisable to diagnose it promptly to prevent further complications or damage to the transmission system.
How to Diagnose the P0887 Code
Diagnosing the P0887 code typically involves the following steps:
- Use an OBD-II scanner to confirm that the P0887 code is present.
- Inspect the wiring and connectors related to the TCM and its relay for any damage or corrosion.
- Test the voltage at the TCM to ensure it is receiving the correct amount.
- Check the operation of the TCM and relay using a multimeter.
Common Repairs for the P0887 Code
Repairs for the P0887 code may include:
- Replacing the Transmission Control Module (TCM)
- Replacing the TCM relay
- Repairing or replacing damaged wiring
How Much Does It Cost to Fix the P0887 Code?
The cost to repair the P0887 code can vary significantly depending on the specific issue. Typically, repair costs can range from $100 to $1,500, depending on whether parts need to be replaced or if there are more extensive wiring issues.
Can I Fix the P0887 Code Myself?
