P0880 OBD-II Trouble Code: Traction Control Module (TCM) Power Input Signal

Check Engine Light

P0880 code definition

The P0880 code refers to an issue with the vehicle's traction control module communication circuit.

What the P0880 code means

A P0880 indicates that the vehicle's Powertrain Control Module (PCM) has failed to receive data from the traction control module communication circuit. Among other things, this system allows the vehicle to calculate an engine's RPM and optimize the delivery of fuel. The traction control system regularly feeds input into the PCM. The trouble code and illumination lamp will be signaled if there's an interruption in this feed.

What causes the P0880 code?

In the majority of cases, this code is caused by a malfunction in the traction control system's activation switch. The source of the problem has also been pinpointed to issues with system-related electrical wiring, including corrosion, disconnection and damage. Damage to the traction control system may be the cause of liquid contact.

What are the symptoms of the P0880 code?

If the vehicle's traction control system is compromised, issues with traction and shifting can be expected. P0880 sufferers report problems with shifting, increased trouble driving on wet or slippery surfaces, and a reduction in the vehicle's fuel efficiency. In addition, for purely diagnostic purposes, the trouble code and illuminated dashboard lamp will occur to help the operator identify the problem.

How does a mechanic diagnose the P0880 code?

A mechanic may initially identify the presence of a P0880 code by using an OBD-II code reader to scan the vehicle computer's trouble log. Because the traction control activation switch is the most common cause of a P0880, it should be inspected first for signs of fault or damage. All system-related wiring and circuit should be inspected for disconnection, damage or corrosion. The traction control module itself can be diagnosed by disconnecting individual components or testing the voltage at different points of the communication circuit.

Common mistakes when diagnosing the P0880 code

In most cases, the traction control switch is to blame for a P0880 code. However, the entire traction control module is occasionally replaced instead. This is a needlessly expensive alternative; the traction switch should be thoroughly inspected before considering other possible causes.

How serious is the P0880 code?

A P0880 may result in significant drivability issues for the vehicle. This is especially true if the driving surfaces are in need of traction control. Wet, slippery or rugged surfaces should be avoided while a P0880 code is in effect. In addition, more severe cases of this code may impede use of the stick shift, rendering the vehicle inoperable.

What repairs can fix the P0880 code?

Additional comments for consideration regarding the P0880 code

The P0880 trouble code only applies to vehicles with an electronic traction control system.
