Code P0267 Mercury Description
The P0267 code for a Mercury indicates an issue with the Cylinder 3 Injector Circuit being detected as low. This means that there is a problem with the fuel injector for cylinder 3 in the engine. The fuel injector is responsible for delivering the correct amount of fuel into the combustion chamber for efficient combustion. When the injector circuit is detected as low, it means that there is a problem with the electrical signal that controls the injector, leading to a potential decrease in fuel delivery to the cylinder.
Common Causes of P0267 Mercury
- Faulty fuel injector for cylinder 3
- Damaged wiring or connectors in the injector circuit
- Malfunctioning Engine Control Module (ECM)
- Clogged fuel filter restricting fuel flow
- Fuel pump failure affecting fuel delivery
Symptoms of P0267 Mercury
- Rough idle
- Hesitation or stumbling during acceleration
- Decreased fuel efficiency
- Engine misfires
- Engine stalling or difficulty starting
How to Fix P0267 Mercury
- Diagnose the specific cause of the issue by performing a comprehensive inspection of the fuel injector, wiring, connectors, and ECM.
- Test the fuel injector for proper operation and replace if necessary.
- Check and repair any damaged wiring or connectors in the injector circuit.
- Replace the fuel filter to ensure unrestricted fuel flow to the injector.
- Clear the diagnostic trouble codes, reset the ECM, and test drive the vehicle to confirm the issue has been resolved.
Cost to Fix P0267 Mercury
The cost of repairing a Cylinder 3 Injector Circuit Low issue can vary depending on the specific cause of the problem and the labor rates in your area. Typically, the cost of replacing a fuel injector can range from $150 to $350 per injector, not including labor. The cost of replacing a fuel filter is generally around $50 to $100. Labor costs can vary, but as a rough estimate, you can expect to pay between $200 and $500 for the repair, including parts and labor.
