This summary uses the existing diagnostic information shown in full below.
Your car's computer is having trouble adjusting the fuel injector for cylinder 2, and it's stuck at the lowest setting it can go.
The engine control module (ECM) is unable to adjust the fuel injector for cylinder 2 beyond its minimum limit, indicating a potential issue with the injector's calibration or performance.
The P02CE code indicates that the ECM has detected that the offset learning for the fuel injector on cylinder 2 has reached its minimum limit. This means the ECM cannot further adjust the injector's fuel delivery to achieve optimal engine performance, which could be due to a malfunctioning injector or related components.
• Engine misfire
• Reduced fuel efficiency
• Rough idle
• Faulty fuel injector
• Wiring issues in the injector circuit
• ECM software issue
ECM: Engine Control Module, the computer that manages engine operations.
Fuel Injector: A component that delivers fuel into the engine's cylinders.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for cylinder 2 fuel injector.
• Test the fuel injector for proper operation.
• Replace the faulty fuel injector.
• Repair or replace damaged wiring or connectors.
• Update ECM software if necessary.
• OBD-II scanner
• Multimeter
• Fuel injector tester

Moderate
• Chevrolet Silverado
• GMC Sierra
• Ford F-150
• Regularly maintain fuel injectors.
• Use quality fuel to prevent injector clogging.
• Perform periodic engine diagnostics.
Engine Performance
• Address the issue promptly to avoid engine damage.
• Consult a professional mechanic if unsure about repairs.
Check with your vehicle manufacturer for warranty coverage on fuel injectors.
This code has been associated with injector calibration issues in certain models, often requiring injector replacement or ECM updates.
Moderate – Should be addressed soon to prevent further engine performance issues.
Driving with engine performance issues can lead to unsafe driving conditions and increased emissions.
• Engine at operating temperature
• Vehicle at idle
The fuel injector for cylinder 2 is located on the engine block, typically accessible by removing the engine cover.
Q: Can I drive with a P02CE code?
A: It's not recommended to drive for long periods with this code, as it can lead to poor engine performance and potential damage.
Q: How can I prevent P02CE from occurring?
A: Regular maintenance and using high-quality fuel can help prevent fuel injector issues.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
