Code P0267 Description

The P0267 diagnostic trouble code (DTC) indicates that there is a low voltage condition in the control circuit of the fuel injector for cylinder 3 in the engine. Each cylinder in the engine has its own fuel injector, which is responsible for delivering the precise amount of fuel needed for combustion. In this case, the control circuit for the fuel injector in cylinder 3 is not receiving the expected voltage, which can lead to improper fuel delivery and affect the engine's performance.

Common Causes of P0267

  1. Faulty wiring or connectors in the injector control circuit
  2. Malfunctioning fuel injector
  3. Issues with the powertrain control module (PCM)
  4. Sensor issues affecting the injector control circuit
  5. Electrical problems such as a blown fuse or relay related to the injector circuit

Symptoms of P0267

  1. Engine misfires or runs rough
  2. Decreased power and acceleration
  3. Poor fuel efficiency
  4. Check Engine Light illuminated
  5. Engine stalling or hesitation

How to Fix P0267

  1. Begin by conducting a thorough visual inspection of the wiring and connectors in the injector control circuit to check for any signs of damage or corrosion.
  2. Test the fuel injector for cylinder 3 to determine if it is functioning properly. This can be done using a multimeter or by performing a fuel injector balance test.
  3. Check the powertrain control module (PCM) for any fault codes related to the injector control circuit and address any issues found.
  4. Inspect related sensors such as the crankshaft position sensor or camshaft position sensor that may impact the fuel injector control circuit.
  5. If necessary, replace any faulty components identified during the diagnostic process, such as wiring, connectors, the fuel injector, or the PCM.

Cost to Fix P0267

The cost of repairing a P0267 code can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, replacing a fuel injector or repairing wiring or connectors can range from $150 to $500, including parts and labor. Additional diagnostic time may also be required to accurately pinpoint the source of the problem, which can add to the overall cost. It's recommended to consult with a professional mechanic for a more precise cost estimate based on the vehicle make and model. Keep in mind that labor rates at auto repair shops can vary, so it's advisable to shop around for the best rates in your area.
