Generic OBD Error Code Details for P0171
System Too Lean
What does this mean?
OBD Code P0171refers to
Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1. Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.
Symptoms
Possible sumptoms of OBD code P0171
You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.
Causes
Possible causes of OBD code P0171
A code P0171 may mean that one or more of the following has happened: •The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. •There could be a vacuum leak downstream of the MAF sensor.
Possible Solutions
Possible solutions include: •In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling •Inspect all vacuum and PCV hoses, replace if necessary •Check for a dirty fuel filter and proper fuel pressure

 

Fan is on all the time. This is without dbt the.worst car ive ever had. So far its had. New plugs. 4 thermostats a coil pack a new catalytic conv. 2 abs sensors. Lambda sensors.

 

what diagnostic equipment is the garage using ???? sounds to me he is using a stand OBD reader or hasnt a clue about diagnostics

 

I use my car as a taxi. So the company ibwork for has its own garage. So not sure what diagnostic he has

 

Vauxhall want 84 quif for diagnostic

 

you local to Manchester ??

 

No glasgow.

 

Looks lke im gonna have to pay the 84 to put it i.to vauxhall

 

get the data list checked I suspect a ECT sensor at fault if the fan is running all the time, as for the p0171 I have a few xep and xer engines with the oil filler cap incorrectly fitted drawing air into the breathing system just a quick one to check.
