Fuel Injector Circuit Malfunction Cylinder 2 (Ford)
What does P1202 mean?
The P1202 code means the vehicle's onboard diagnostic system has detected: Fuel Injector Circuit Malfunction Cylinder 2 (Ford). This is a moderate severity code.
Common Symptoms
- Check Engine Light on
- Cylinder 2 misfire
- Rough idle and vibration
- Loss of power
- Poor fuel economy
Probable Causes (Ranked by Likelihood)
- Faulty cylinder 2 fuel injector Very High
- Open or shorted wiring to cylinder 2 injector High
- Corroded connector at cylinder 2 injector Moderate
- PCM injector driver fault Moderate
- Harness damage from engine heat or vibration Low
Step-by-Step Diagnostic Procedure
-
Measure cylinder 2 injector coil resistance
-
Inspect the cylinder 2 injector connector for corrosion
-
Use a noid light to check for injector pulse at cylinder 2
-
Swap the cylinder 2 injector with another to test if the fault follows
-
Check wiring from PCM to cylinder 2 injector for continuity
Frequently Asked Questions
Can I swap injectors to diagnose P1202?
Yes. Swapping the cylinder 2 injector with one from another cylinder is an excellent diagnostic technique. If the code moves to the new cylinder, the injector is faulty. If it stays on cylinder 2, the wiring or PCM is the issue.
How much does a Ford fuel injector cost?
Individual fuel injectors for Ford vehicles typically cost $30 to $100 each. Direct injection injectors (GDI) on newer models can cost $80 to $200 each. Labor adds $100 to $300 depending on accessibility.
Can I clean a faulty injector instead of replacing it?
If the injector has a mechanical clog, professional ultrasonic cleaning may restore it. However, if P1202 indicates an electrical circuit fault (open or short in the coil), cleaning will not help and the injector must be replaced.
