Cylinder 10 Injector Restricted
The P02C0 code indicates that the Engine Control Module (ECM) has detected a restriction in the fuel injector for cylinder 10. This means the injector is not delivering the proper amount of fuel, often due to clogging or internal damage. The ECM monitors fuel flow and pressure, and when it detects an imbalance or reduced flow, it sets this code. A restricted injector can cause lean misfires, reduced power, and increased emissions.
01. Most Common Causes
- Clogged fuel injector from debris or carbon buildup
- Failed injector internal components (stuck pintle, coil failure)
- Contaminated fuel (water, dirt, or poor quality fuel)
- Fuel filter restriction causing low pressure to injector
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine misfire or rough idle, especially on cylinder 10
- Reduced engine power and poor acceleration
- Increased fuel consumption and possible hesitation
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data to confirm P02C0 and check for related codes.
Step 2: Perform a fuel injector balance test using a scan tool to measure fuel flow on cylinder 10 vs others.
Step 3: Visually inspect injector electrical connector and wiring for damage or corrosion.
Step 4: Remove injector and bench test for spray pattern and flow rate; clean or replace if restricted.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances. A restricted injector can cause misfires, catalytic converter damage, and poor fuel economy. Have it diagnosed and repaired promptly.
How much does it cost to fix?▼
Diagnosis typically costs $50-$150. Injector cleaning may cost $100-$200, while replacement of a single injector can range from $200-$600 including labor, depending on vehicle.
