This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble adjusting how much fuel goes into the first cylinder of the engine. It's like trying to balance a see-saw, but one side is stuck at the bottom.
The engine control module (ECM) is unable to adjust the fuel injector's offset for cylinder 1, and it's stuck at its minimum limit.
The P2C52 code indicates that the ECM has detected that the fuel injector offset learning for cylinder 1 has reached its minimum limit. This means that the ECM is unable to adjust the fuel injector's operation to achieve optimal performance, possibly due to a mechanical or electrical issue.
• Check Engine Light on
• Poor fuel economy
• Rough engine idle
• Faulty fuel injector
• Wiring issues or poor connection
• ECM software issue
ECM: Engine Control Module
Fuel Injector: A device that sprays fuel into the engine's cylinders
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for the fuel injector.
• Test the fuel injector for proper operation.
• Replace the faulty fuel injector.
• Repair or replace damaged wiring or connectors.
• Update the ECM software if necessary.
• OBD-II scanner
• Multimeter
• Fuel injector tester

Engine Performance
• Get the issue diagnosed by a professional mechanic.
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
Check with your vehicle manufacturer for warranty coverage on fuel injectors.
This code has been associated with vehicles experiencing injector issues due to wear and tear or electrical problems.
Moderate – Should be addressed soon to avoid potential engine performance issues.
Ignoring this code can lead to increased emissions and potential damage to the engine.
• Engine at operating temperature
• Vehicle in a safe environment for testing
The fuel injector for cylinder 1 is located on the engine block, typically near the intake manifold.
Q: Can I drive with a P2C52 code?
A: It's not recommended to drive with this code as it can lead to poor engine performance and increased emissions.
Q: How do I clear a P2C52 code?
A: After repairs, the code can be cleared with an OBD-II scanner, but it may return if the issue is not resolved.
