Check These First (Before Buying Parts)
- Visually inspect the electrical connector on cylinder 11's fuel injector for any signs of damage, corrosion, or if it's loose.
- Check the wiring leading to the injector for any frayed, cut, or pinched spots.
How to Diagnose P0289
- 1Visually inspect the wiring harness and connector for cylinder 11's fuel injector for any damage, corrosion, or loose connections.
- 2Using a multimeter, check the resistance of the cylinder 11 fuel injector. Compare it to specifications and other injectors.
- 3With the engine off and key on, check for proper voltage at the cylinder 11 injector connector (usually battery voltage on one wire).
- 4If possible, swap the cylinder 11 injector with an injector from another cylinder and see if the code moves to the new cylinder location.
- 5If all other checks pass, test the PCM's injector driver circuit for cylinder 11 using a scan tool or oscilloscope.
P0289 on Popular Vehicles
Toyota Camry
AllP0289 indicates an issue with cylinder 11. Toyota Camry vehicles do not have 11 cylinders, so this code is not applicable to them. If you see this code on a Camry, it may be a scanner error or a manufacturer-specific code with a different meaning.
N/A
Ford F-150
AllP0289 indicates an issue with cylinder 11. Ford F-150 trucks (even V8s) do not have 11 cylinders, so this code is not applicable to them. This code is typically found on larger V10/V12 engines or specific manufacturer numbering schemes.
N/A
Chevrolet Silverado
AllP0289 indicates an issue with cylinder 11. Chevrolet Silverado trucks (even V8s) do not have 11 cylinders, so this code is not applicable to them. This code is typically found on larger V10/V12 engines or specific manufacturer numbering schemes.
N/A
General Note for V10/V12 Engines
AllFor vehicles with 11 or more cylinders (e.g., some V10s, V12s, or specific manufacturer numbering), P0289 points directly to a problem with the fuel injector or its circuit for cylinder 11. Common issues include a failed injector, damaged wiring, or a faulty PCM driver.

Frequently Asked Questions
What does P0289 mean?
P0289 indicates that your vehicle's engine computer (PCM) has detected an electrical problem with the fuel injector circuit for cylinder 11, specifically a higher-than-expected voltage or an open circuit.
Can I drive with P0289?
Limit driving, fix within a few days. Driving with a P0289 code means cylinder 11 is likely misfiring. This can lead to reduced power, poor fuel economy, and can quickly damage your catalytic converter due to unburned fuel entering the exhaust.
Will P0289 clear itself?
No, P0289 will not clear itself. This code indicates a hard electrical fault that requires diagnosis and repair. The Check Engine Light will remain on until the underlying issue is resolved and the code is cleared, either by the PCM after several drive cycles or with a scan tool.
How do I fix P0289 myself?
Start by visually inspecting the wiring and connector for cylinder 11's fuel injector. If no obvious damage, test the injector's resistance with a multimeter. If the injector is faulty, you'll need to replace it. If the wiring is damaged, repair it. A scan tool is helpful for clearing the code and monitoring live data.
How much does it cost to fix P0289?
The cost to fix P0289 varies. If you do it yourself, replacing a fuel injector typically costs $60-$210 for the part. Professional repair, including diagnosis and labor, usually ranges from $400-$800, depending on the vehicle and shop rates.
P0289 keeps coming back - why?
If P0289 keeps returning, it means the root cause was not fully addressed. Common reasons include a faulty replacement injector, a hidden wiring issue that wasn't properly repaired, or a rare PCM fault that was overlooked during initial diagnosis.
Will P0289 fail emissions/smog test?
Yes, P0289 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on is an automatic failure in most jurisdictions, and a misfiring cylinder will also lead to elevated emissions.
What's the difference between P0289 and P0311?
P0289 specifically indicates an electrical circuit problem with the cylinder 11 fuel injector (Circuit High). P0311, on the other hand, indicates a misfire detected in cylinder 11. While a P0289 will almost certainly cause a P0311, P0311 can be caused by many other issues besides an injector circuit problem, such as a bad spark plug, ignition coil, or low compression.
P0289 on Ford F-150?
P0289 indicates an issue with cylinder 11. Ford F-150 trucks (even V8s) do not have 11 cylinders, so this code is not applicable to them. If you encounter this code on an F-150, it is likely a scanner error, a manufacturer-specific code with a different meaning, or a misinterpretation. This code is typically found on larger V10/V12 engines or specific manufacturer numbering schemes.
Questions to Ask Your Mechanic
Did you check the resistance of the cylinder 11 fuel injector and compare it to specifications?
Good answer: Yes, the resistance was out of spec, indicating an internal fault in the injector. We've confirmed it needs replacement.
What did you find when inspecting the wiring harness and connector for cylinder 11's injector?
Good answer: We found some corrosion in the connector pins, which was causing an open circuit. We've cleaned and repaired the connection.
Have you ruled out the PCM as a potential cause?
Good answer: Yes, we've tested the injector driver circuit from the PCM and confirmed it's sending the correct signal. The issue is definitely with the injector itself or its wiring.

Cost of Waiting
Ignoring P0289 and the resulting misfire will send unburned fuel into your exhaust system. This rapidly overheats and destroys your catalytic converter, turning a $60-$200 injector job into a $800-$2,500 converter replacement. You will also experience significantly worse fuel economy and reduced engine performance.
While You're In There...
These seals are removed and often damaged during injector replacement. Replacing them prevents fuel leaks and ensures a proper seal.
If the fuel rail needs to be removed to access the injector, replacing these seals prevents future fuel leaks and is minimal extra labor.

Your Next Steps
Step 1: Perform a thorough visual inspection of the cylinder 11 fuel injector's wiring and connector. Look for any obvious damage, corrosion, or loose connections.
Step 2: If the visual inspection doesn't reveal the issue, use a multimeter to test the resistance of the cylinder 11 fuel injector. Compare the reading to your vehicle's specifications or to a known good injector from another cylinder. If the resistance is out of spec, replace the fuel injector.
Step 3: If the injector resistance is good, check for proper voltage at the injector connector with the key on. If voltage is incorrect, trace the wiring back to the PCM for damage. If wiring is good, the PCM may be at fault (less common).
