P0274 Code - Cylinder 5 Injector Circuit High

What Does P0274 Mean?

OBD-II Code Decreased engine performance is defined as a Cylinder 5 Injector Circuit High

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 P0274.

What are the common causes of P0274 ?

• An air leak forward of the DPF will change the sensor readings resulting in the code
• Rusty exhaust systems, cracked exhaust manifolds or damaged or missing gaskets or donuts will cause air leaks.
• Faulty IMRC actuator/sensor

How do you troubleshoot P0274 ?

While fuel economy was increased, acceleration was seriously compromised, and the loss of engine vacuum led to a dangerous loss of braking assist when the P0274 code system was in four-cylinder mode. In addition to these issues, while the company proposed a hydraulically controlled system that could be switched from within the car, the version they implemented had to be manually changed in the engine compartment using hand tools.
