Injector Data Incompatible (P2696)
The P2696 code indicates that the Engine Control Module (ECM) has detected a mismatch between the expected and actual injector data, typically due to incorrect injector coding or replacement of injectors without proper calibration. This can lead to improper fuel delivery, affecting engine performance and emissions.
1. Most Common Causes
- Injector replacement without proper coding
- Incorrect injector part number installed
- Faulty ECM or wiring issue
- Corrupted injector calibration data
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or misfire
- Poor fuel economy
- Reduced engine power
3. Step-by-Step Diagnosis
Step 1: Scan the ECM for codes and freeze frame data.
Step 2: Verify injector part numbers match OEM specifications.
Step 3: Use a diagnostic tool to reprogram or code injectors to the ECM.
Step 4: Inspect wiring and connectors for damage or corrosion.
