P0294 Code - Cylinder 12 Injector Circuit Low

What Does P0294 Mean?

OBD-II Code Decreased engine performance is defined as a Cylinder 12 Injector Circuit Low

The engine control module (PCM) has special transistors called "drivers" to turn the Fuel Injectors on and off in the Fuel Injection System. If the PCM cannot control the fuel injector, it will set code P0294.

What are the common causes of P0294 ?

Possible causes of this fault code may include:

• A bad fuel injector
• A clogged or dirty fuel injector
• A short or open in the fuel injector wiring or harness
• A malfunction in the PCM’s fuel injector driver
• A damaged or loose connector at the fuel injector

How do you troubleshoot P0294 ?

Now, clear the codes and test-drive the vehicle to see if the code is reset. Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector. Replace the oxygen sensor that is downstream from the catalytic converter on the side of the engine that does not contain cylinder #1. Also, if a oxygen sensor code stating "heater circuit malfunction" the sensor has most probably failed.
