U2967 Code:

OBD-II Diagnostic Network (U) Trouble Code

Possible Cause

The most common causes of this U2967 code being stored are due to a defective input speed sensor or output speed sensor. Other common causes include shorted, open, corroded, or damaged wiring circuits or connectors.

Common Symptoms

  1. If the fuel shutoff switch and all system circuitry checks out, suspect a defective PCM (or other related controller)
  2. This signal is systematically forwarded to affected control modules that utilize the data to accomplish various other tasks
  3. Look for shorted or burned wiring and replace circuitry and connectors as required
  4. As exhaust temperature decreases (with the engine off), circuit resistance increases and the feedback voltage signal to the PCM decreases

Similar Problems

IC Module 4X Ref Circuit Intermittent, No Pulses
Air Conditioning (A/C) Clutch Feedback Circuit High Voltage
PCM Stack Overrun

U2967 Troubleshooting

If there is a clicking noise when you attempt to start the engine and the engine does not crank, it typically means there is something wrong with the battery, such as a low or discharged battery or corroded or loose battery cables. If the engine cranks when you attempt to start the car, but fails to turn over, this may mean there is a problem with the fuel or ignition. Other common reasons an engine may fail to start include a failure of the starter motor relay, a clogged fuel filter, a defective fuel pump or an ignition switch failure. U2967 OBD2 may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.

How to turn off U2967 check engine light ?

There are two ways to turn off the check engine light:

A repair technician can do so once repairs have been made.
The OBD II can automatically turn it off when it fails to detect the problem after several diagnostic cycles.
