P0288 Code - Cylinder 10 Injector Circuit Low

What Does P0288 Mean?

OBD-II Code Decreased engine performance is defined as a Cylinder 10 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 P0288.

What are the common causes of P0288 ?

The most common cause of this code is damage to wiring caused by wildlife. The warm area atop the engine provides shelter for small animals, where they proceed to gnaw the wiring for some strange reason. Other causes include a faulty fuel injector, clogged fuel injector, corroded or loose electrical wiring or connector faces, or a faulty fuel injector driver in the PCM.

How do you troubleshoot P0288 ?

Once the P0288 code has been detected, the first step to take is to try to determine whether the problem is with the fuel injector itself, or with its associated electrical connectors and wiring. The electrical connector, and the harness, should be inspected first to see if anything has become loose or has become corroded. If everything appears to be normal, the next step will be to see if the fuel injector is operating.



With the engine running, listen to the injector to see if it is working. You can usually tell if it is by placing the blade of a long-handled screwdriver against it, placing the handle against your ear, and listening for a rather pronounced clicking sound.

If you hear nothing, the injector has either failed, or it is not receiving electrical power. A voltmeter will indicate if power is present. If no voltage is present, the wiring to the fuel pump relay could be at fault. If power is present, check both terminals to see if the PCM injector driver is operating. If it is, the fuel injector needs to be flushed out or replaced. Your local auto parts store will usually have a direct injector flushing kit in stock, or one can purchased online if necessary. If cleaning the injector does not resolve the issue, it will need to be replaced.
