Error Code P0887: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0887 can be elucidated as TCM Power Relay Control Circuit High. The P0887 code is a generic OBD-II trouble code which would suggest an issue with the traction control module communication circuit. The data is sent to the powertrain control module as well as other control modules about the traction control system and usage by the traction control module communication circuit. This information would be taken into account by the PCM as well as various other control modules when calculating things such as the optimal engine timing and the right fuel delivery strategy. Now when the PCM or any of the other control modules would not receive the data from the traction control module communication circuit, then it would give rise to the P0887 fault code.

Want to learn something more about the P0887 fault code? This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

What causes this problem with the TCM Power Relay Control Circuit High?

• Some issues related to the defective, burnt, or shorted wiring
• Malfunctioning TCM power control relay
• Unusable transmission control module

1. Body Control Module Component - Defective car Body Control Module Component can be a major reason why P0887 code depicts. So, make sure to replace it online so that you don’t have to face any further issues.
2. Electronic Control Unit - Everything is okay with the PCM and still OBD code P0887 triggering? Then there must be some defects in Electronic Control Unit. Replace them as soon as possible.
3. Auto Transmission Control Module - P0887 code flashing? Get your Auto Transmission Control Module inspected from a mechanic.
4. Powertrain Control Module - If everything is alright with Auto Transmission Control Module, then there is surely some defect in Powertrain Control Module. Get it replaced before the situation gets worse.
5. Engine Control Module - P0887 code can display due to some issues in the Engine Control Module. So, it is very important to replace the Engine Control Module with us at equitable prices.

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• There can be an appearance of the warning light
• The transmission might remain in “limp mode” resulting in immobilizing the vehicle
• There can be bad acceleration
• Some applications might remain stuck in one gear

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• You must fix the defective engine vacuum
• Make sure to mend the faulty transmission control module
• It is essential to restore the flawed engine control module/powertrain control module
• Repair or replace the quirky electronic control unit
• Rehabilitate the defaults in the body control module component

Do you want to diagnose the P0887 trouble code easily? Here are some steps which you should follow in order to diagnose this fault code:

Are you thinking what the full form of CAN is? We are here to help you out. CAN stands for “controller area network.” A communication bus is represented by CAN which would allow a lot of microcontrollers to communicate with one another without the requirement for a host computer. It is a message-based agreement originally designed for vehicle utilization.

It is a compound conglomeration of wiring harnesses and connectors used as a pipeline of information shared between two or more vehicle control modules. Virtually every electrical function is controlled by these controllers of the vehicle, and the powertrain control module is the chief controller.

Input data from a number of sensors is received by the control modules and emit output signals to system constituents and other control modules. We can understand this better with the help of an example. An input signal is received by the PCM from the vehicle speed sensor. This signal is orderly moved forward to the affected control modules that utilize the data to accomplish a lot of other tasks.

The code should then be cleared up and the vehicle should be operated to check if it is returning back again or not. This would prove to be very helpful to decide whether or not the failure is intermittent. Then the vehicle should be taken out for a test drive to check if the code is returning back again or not. If the code does not return back immediately, then it would result in an intermittent condition.

Common Mistakes When Diagnosing the P0887 Code

• Non-observance of the transmission control module
• There can be some faults in the wiring
• Negligence in the transmission control module relay
