P1214 CHEVROLET - Injection Pump Timing Offset
P1214 CHEVROLET Possible Causes
- Fuel Injection Pump Gear Alignment
- Fuel Filter Restriction
- Transfer Pump Inlet Restriction
- Faulty Fuel Injection Pump
How is the P1214 CHEVROLET code repair?Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Perform Top Dead Center (TDC) Offset Procedure to ensure proper injector pump timing. Use the procedure listed below:
1. Perform anti-theft (PASSLOCK) relearn procedure first.
2. Install suitable scan tool.
3. Using the scan tool, clear any DTCs present.
4. Start engine and bring to operating temperature. Shut engine down.
5. Turn ignition switch to the ON position, engine off (not running).
6. Fully depress throttle for at least 45 seconds.
7. Turn ignition switch to the OFF position for 30 seconds.
8. Restart engine. Using scan tool, verify that TDC offset has been cleared to zero.
9. Start engine and bring to operating temperature, engine RPM less than 1500.
10. Using scan tool, verify that TDC offset is between negative .25 to negative .75. If TDC offset is within specs, relearn procedure is complete. 11. If TDC is not within specs, it will be necessary to reset the injector
pump timing. Follow the procedure outlined in the shop manual.

P1214 CHEVROLET MeaningThe Powertrain Control Module (PCM) monitors crankshaft position through the Crankshaft Position (CKP) sensor. The CKP info is used to determine the amount of injection timing offset necessary for proper operation. This code will set if the TDC-Offset is greater than +2.46 degrees or less than -2.46 degrees. Sounds like you need to perform a TDC-Offset Learn procedure.
