What Does P2694 Mean?
The ECM has detected that the stored calibration data for the cylinder 9 fuel injector does not match the expected parameters or is corrupted. This code is only applicable to vehicles with 9 or more cylinders and typically occurs after injector replacement when programming was not completed.
Common Causes
50%
Injector replaced but not programmed or calibrated to ECM
25%
Corrupted injector calibration data in ECM memory
15%
Wrong injector installed for vehicle application
10%
ECM software update required or failed programming procedure
Diagnostic Steps
1
Step 1: Verify injector part number matches vehicle specifications and OEM requirements
2
Step 2: Check service history to determine if cylinder 9 injector was recently replaced
3
Step 3: Attempt to reprogram/calibrate injector data using manufacturer scan tool or software
4
Step 4: If programming fails, verify ECM software is current version and update if necessary
5
Step 5: Clear codes and test drive; if code returns, replace ECM or injector as indicated by diagnostic results
Estimated Repair Cost
$150 - $800

The most common cause of P2694 (Cylinder 9 Injector Data Incompatible) is: Injector replaced but not programmed or calibrated to ECM
Typical repair costs for P2694 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may experience rough running, reduced power, and increased emissions but is generally safe to drive short distances. Extended operation may cause catalytic converter damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2694 to identify the root cause.
