P0289 code definition

The DTC P0289 code indicates that the number 10 cylinder is experiencing an above average amount of current at the fuel injector.

What the P0289 code means

Code P0289 means that the fuel injector circuit for the number 10 cylinder fuel injector is drawing too much current. This is a generic code, which means it is common to all automakers. However, due to differences in technology used across different makes and models, the prognosis may be different for some vehicles. The code is stored when the car’s computer (ECM) detects higher than usual voltage at the circuit for fuel injector 10.

What causes the P0289 code?

There are quite a few different potential causes for a P0289 code. These include:

  • A fault with the injector’s wiring harness
  • A clogged or dirty fuel injector
  • A fault with the connector between the wiring harness and the fuel injector
  • A short to ground in the fuel injector
  • A failed fuel injector
  • A failed ECM (this is very rare)

What are the symptoms of the P0289 code?

The P0289 code can be accompanied by several different symptoms. The Check Engine light will most likely turn on when the code is set. In addition, the other symptoms possible include:

How does a mechanic diagnose the P0289 code?

The process of diagnosing the underlying problem usually starts by clearing the code from the computer. A short test drive should then be undertaken to determine if the code resets. If it does, then the mechanic will conduct a visual inspection of the fuel injector, the wiring harness and the connector. The connector should be inspected thoroughly, and the mechanic should check for corroded, bent or broken pins.

Often, the problem is actually a faulty or clogged fuel injector, particularly in older model vehicles. Cleaning the affected injector can eliminate the code and restore normal functionality to the engine.

Once the repair has been made, the mechanic should again clear the code from the computer and test drive the vehicle to ensure proper operation of the fuel injector, and that the code is not reset again.

Common mistakes when diagnosing the P0289 code

The most common mistake made when diagnosing the P0289 code is for the mechanic to automatically assume that the problem is a dirty fuel injector. This can lead to lost time attempting to clean an injector that has actually failed. Another common mistake is not checking the fuel injector/wiring harness connector for damage or corrosion.

How serious is the P0289 code?

The P0289 code is serious, although it will not prevent the vehicle from being driven. However, understand that damage can occur to the engine if the cylinder is not firing correctly due to a faulty fuel injector or injector connector. It is best to have the problem diagnosed and repaired immediately.

What repairs can fix the P0289 code?

Several different repairs are possible to correct code P0289, depending on the underlying problem. These can include:

  • Replacing a failed fuel injector
  • Cleaning a dirty/clogged fuel injector
  • Repairing or replacing a damaged or corroded connector
  • Replacing damaged wiring to the fuel injector (rare)

Additional comments for consideration regarding the P0289 code

The most common problem causing a P0289 code is damage or dirt within the fuel injector. In some instances, this is related to the addition of ethanol in fuel, as it reduces lubrication from oil within gasoline. This can cause premature wear within the fuel injector, leading to early failure.
