P0200: Injector Circuit Malfunction
Can you still drive? Not recommended for extended driving. A dead injector causes misfires that can damage the catalytic converter.
What Does P0200 Mean?
Code P0200 is a general code indicating a malfunction detected in the fuel injector circuit. Unlike injector-specific codes (P0201-P0212), P0200 does not pinpoint which cylinder is affected. The ECM has detected an electrical problem such as abnormal resistance or an open/short in one or more injector circuits.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.

- Failed fuel injector
- Open or shorted injector wiring
- Corroded injector connector
- Faulty ECM injector driver
- Poor ground connection in injector circuit
Symptoms
- Check engine light on
- Engine misfires
- Rough or unstable idle
- Loss of power
- Increased fuel consumption
Diagnostic Steps
- 1Read freeze frame data to identify operating conditions when fault occurred
- 2Measure resistance of each fuel injector (typical 11-18 ohms for high-impedance injectors)
- 3Check for voltage at each injector connector with key on
- 4Inspect injector wiring harness for damage, chafing, or shorts
- 5Test ECM injector driver outputs using a noid light
- 6Perform injector balance test to identify weak or dead injectors

1 Active Recall — 2026 Ford F-150
The following NHTSA safety recalls have been issued for this vehicle. Contact your dealer to check if your vehicle is affected.
ELECTRICAL SYSTEM: INTEGRATED TRAILER BRAKE CONTROL
Ford Motor Company (Ford) is recalling certain 2021-2026 F-150, 2022-2026 F-250 SD, F-350 SD, F-450 SD, F-550 SD, Maverick, 2024-2026 Ranger, 2023-2026 F-600 SD, 2022-2027 Lincoln Navigator, Expedition, and 2026 E-Transit vehicles. When towing a trailer, the integrated trailer module (ITRM) may lose communication with the vehicle, possibly causing a loss of brake and turn signal lights, or a loss of brake function. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, " Lamps, Reflective Devices, and Associated Equipment."
Remedy: The integrated trailer module software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. Owner notification letters are expected to be mailed March 17, 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 26C10. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning March 17, 2026.

Frequently Asked Questions
What is the difference between P0200 and P0201?
P0200 is a general injector circuit code that does not specify which cylinder is affected. P0201 specifically points to the cylinder 1 injector circuit. Further diagnosis is needed with P0200 to identify the affected cylinder.
How much does a fuel injector cost?
Individual fuel injectors typically cost $50-$200 each depending on the vehicle. Many mechanics recommend replacing all injectors at the same time if one has failed, which increases the total cost.
