I was reving it kinda high. Could it have something to do with the gas I put in it last?

P2191 - System Too Lean at Higher Load Bank 1

Possible causes

- Leaking fuel injector or pressure regulator
- High fuel pressure condition
- Faulty front HO2S
- Leak in exhaust system
- MAF sensor faulty


Help with Possible causes What does this mean?
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

In order to provide the best possible combination of drivability, fuel economy and emission control, the PCM uses a closed loop air/fuel metering system. The PCM monitors the HO2S signal voltage and adjusts fuel delivery based it in closed loop fuel control. Changes in fuel delivery will be indicated by the long-term and the short-term fuel trim values. The ideal fuel trim value is around 0%. The PCM will add fuel when the HO2S signal is indicating a lean condition. Additional fuel is indicated by fuel trim values that are above 0%. The PCM will reduce fuel when the HO2S signal is indicating a rich condition. Reduction in fuel is indicated by fuel trim values that are below 0%. The DTC relevant to fuel trim will be set when the amount reaches excessive levels because of a lean or rich condition.

What scanner are you using; if you try a vw type scanner, you may get some more specific type codes that would be more helpful.

What year/model/engine code is your new beetle; please fully fill out your member info (right corner, under join date/location), so we can help you more intelligently now and in the future.

You could start; your troubleshooting process, by testing the pressure regulator and fuel pressure, to see if it is spec:

Also Code 2177!

Code 2177 is there too.

Possible Source

Upper Limit:
intake air leakage
exhaust system air leakage
low fuel pressure
defective heated oxygen sensor (HO2S)
Lower Limit:
intake air leakage
high fuel pressure
leaking injectors
defective mass air flow (MAF) sensor
contaminated engine oil
oil level too high
defective heated oxygen sensor (HO2S)

Any thoughts? I will look for a defective hose tomorrow. I think the previous owner left it exposed.
