P12BE - Cylinder 6 Injection Timing Advance
P12BE Possible Causes
- Contaminated or improper fuel quality
- Worn base engine components or differences in cylinder compression
- Faulty Fuel Injector
- Fuel Injector harness is open or shorted
- Fuel Injector circuit poor electrical connection
How is the P12BE 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.
What is the cost to diagnose the P12BE code
Labor: 1.0The cost to diagnose the P12BE code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

P12BE MeaningThe Engine Control Module (ECM) has the ability to learn injector timing performance. With the engine at operating temperature and in closed throttle decel mode, the ECM will pulse each injector individually and measure the changes in rotational speed of the crankshaft using the input from the Crankshaft Position Sensor (CPS). The ECM will run this diagnostic under three different fuel rail pressures for each injector. The ECM will adjust the timing of fuel delivered by each injector to obtain the desired RPM increase. The ECM stores the injector timing value required to increase the crankshaft speed by the desired RPM. If the ECM cannot control an increase in RPM for a given injector the appropriate code will set for that injector.
