[SOLVED] Fixing U2016 Code: Powertrain Control Module Short To Ground

The automobile fault code u2016 indicates a problem with the Overhead Trip Computer (OTC) or Message Center. The most common symptom is the Engine Light ON or Service Engine Soon Warning Light.

The cause of this fault code could be a faulty OTC, an open or shorted OTC harness, or a poor electrical connection in the OTC circuit.

The importance of repairing this issue lies in the fact that it can affect the accuracy of the vehicle’s trip computer and other related systems. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins. The repair time is estimated to be around 1.0 hour.

To interpret the fault code, one needs to check the possible causes listed above and visually inspect the related components.

  • The automobile fault code u2016 can be caused by a faulty Overhead Trip Computer (OTC) or Message Center.
  • It can also be caused by an open or shorted Overhead Trip Computer harness.
  • Additionally, a poor electrical connection in the Overhead Trip Computer circuit can also trigger this fault code.

Here are some possible fixes for the automobile fault code u2016:

  • To fix the automobile fault code u2016, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The factors that influence the cost of diagnosing and fixing the automobile fault code u2016 based on the repair time are: – The estimated repair time is 1.0 hour. – Auto repair shops usually charge between $75 and $150 per hour. – The cost may vary depending on the location and reputation of the repair shop. – The type of vehicle and the complexity of the repair may also affect the cost. – Additional parts or labor required for the repair may increase the cost.

The u2016 fault code is related to the Powertrain Control Module (PCM) in your automobile. The PCM is responsible for monitoring the signal from the Overhead Trip Computer (OTC) or Message Center. If the PCM detects that the signal from the OTC is short to ground, it will set the u2016 fault code.

This fault code indicates that there is a short circuit between the PCM and the ground, which can cause various issues with your vehicle’s performance.

It is important to have this issue diagnosed and repaired by a qualified mechanic to prevent further damage to your vehicle.
