P021E Code - Cylinder 11 Injection Timing
Quick Answer
The P021E diagnostic trouble code (DTC) specifically relates to Cylinder 11 Injection Timing. Common causes include Faulty fuel injector: A malfunctioning fuel injector in cylinder 11 can disrupt the injection timing, Wiring or electrical issues: Poor connections or damaged wiring to the fuel injector or ECM can cause timing discrepancies, ECM/PCM malfunction: A problem with the engine control module or powertrain control module may lead to incorrect injection timing. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P021E Description
The P021E diagnostic trouble code (DTC) specifically relates to Cylinder 11 Injection Timing. This code indicates that there is an issue with the injection timing for the fuel delivery system in cylinder 11 of the engine. Injection timing is crucial for the proper operation of the engine, as it determines when the fuel is injected into the combustion chamber. When the injection timing is off, it can lead to poor engine performance, decreased fuel efficiency, and potential long-term damage to the engine components.
Common Causes of P021E
- Faulty fuel injector: A malfunctioning fuel injector in cylinder 11 can disrupt the injection timing.
- Wiring or electrical issues: Poor connections or damaged wiring to the fuel injector or ECM can cause timing discrepancies.
- ECM/PCM malfunction: A problem with the engine control module or powertrain control module may lead to incorrect injection timing.
- Sensor issues: Faulty crankshaft position sensor, camshaft position sensor, or intake air temperature sensor can affect injection timing.
Symptoms of P021E
- Decreased engine performance: The engine may run rough, lack power, or have difficulty accelerating.
- Poor fuel efficiency: The vehicle may experience a decrease in fuel economy due to improper injection timing.
- Rough idle: The engine may idle erratically or have a noticeable vibration at idle.
- Engine misfires: Misfires may occur in cylinder 11, leading to a loss of power and potential damage to the catalytic converter.
- Check engine light: The check engine light may illuminate on the dashboard to indicate the presence of the P021E code.
How to Fix P021E
- Diagnose the issue: Use a diagnostic scan tool to retrieve the trouble codes and perform a thorough inspection of the fuel injector, wiring, and sensors related to cylinder 11.
- Test fuel injector: Test the fuel injector in cylinder 11 to ensure proper operation and fuel delivery.
- Check wiring: Inspect the wiring harness for any damage, corrosion, or loose connections that may be affecting the injection timing.
- Verify sensor readings: Test the crankshaft position sensor, camshaft position sensor, and intake air temperature sensor to ensure they are providing accurate data to the ECM.
- Clear codes and test drive: After repairing or replacing any faulty components, clear the DTCs from the ECM and test drive the vehicle to verify that the injection timing issue has been resolved.
Cost to Fix P021E
The cost of repairing the P021E code can vary depending on the specific cause of the issue. In general, replacing a faulty fuel injector can range from $150 to $500 per injector, while addressing wiring or sensor issues may cost between $100 and $300. Labor costs for diagnosis and repair can add an additional $100 to $300, depending on the shop's hourly rates. Overall, the total repair cost for the P021E code may range from $300 to $1000 or more. It is recommended to consult with a qualified mechanic or dealership for a more accurate estimate based on your vehicle's make and model. Labor rates at auto repair shops can vary, so it's advisable to inquire about hourly rates in your area to get a better idea of the total repair costs.
