What does P0201 mean?

Each fuel injector is an electric valve that the computer opens many times a second. This code means the computer saw an electrical problem in the circuit for the cylinder 1 injector.

The computer tried to control the part and saw an electrical fault, usually an open circuit.

Codes are a starting point. They tell you which test failed, not which part to replace. Check for other stored codes and fix those in a sensible order.

Symptoms

  • Check engine light
  • Misfire on that cylinder
  • Rough idle
  • Loss of power

Common causes

  • Open circuit in the solenoid or its wiring
  • Unplugged or corroded connector
  • Blown fuse feeding the component
  • Failed component

How to diagnose P0201

  1. Check the fuse that feeds the component.
  2. Measure the component's resistance and compare it with the service spec.
  3. Check for power at the connector with the key on, and for a broken control wire back to the computer.
  4. Measure the injector's resistance and compare with spec (many gasoline port injectors are about 11-18 ohms).
  5. Use a noid light to see if the computer is pulsing the injector.

How to fix it

  • Repair wiring or connector
  • Replace the injector

Estimated repair cost

Likely repairs for P0201 run from about $100 to $600, depending on the cause.

RepairTypical range (parts + labor)
Diagnostic fee (scan + testing)$100 - $200
Wiring/connector repair$100 - $400
Fuel injector replacement (gasoline, one)$200 - $600

These are rough US estimates for an independent shop in 2026, based on typical parts prices and standard labor times. Dealers, big trucks, luxury brands and high-cost areas often run higher. They are not quotes. Use the repair cost estimator to adjust for your vehicle.

How serious is P0201?

High severity

Expect a misfire. Short trips are possible, but get it fixed soon to protect the catalytic converter.
