Hello, I’m new to the forum and to the Porsche community (previously drove BMW). I have an issue with a Cayenne S 9YA, V6 324 kW. The car shows a fault with injector no. 3 – error P02F000: Cylinder 3 fuel injector – Unreliable signal. After a few seconds, it also throws P036300: Misfire detected, injector locked out.

Does anyone have any idea what could be wrong? I’ve checked the wiring from the injector to the ECU.

 

Please tell us everything about the car.

Might be one of the highest miles 9Y0s so far...

 

The km or miles have not been reported yet. The 324kw is kilowatt hours and converts to 434 hp. I am curious about the km or miles since I have not read of the problem the OP is having and I have had a 2021 Cayenne S for 5 years and plan to keep it another 5.

 

Car has 178000 km

What services have been done in the past year? - I bought it month ago... all serrvices are done in Porsche service

When was the battery most recently replaced? The codes look like a weak battery.

Do you have any problems with the car running? Rough idle, poor fuel economy, error messages on the display?

Clear all the codes and keep driving. If they return replace the battery.

I enjoyed the 2 times I visited your beautiful country and stopped in Ljubljana. The strukli is good!
