Most auto repairs shops charge between $75 and $150 per hour. When is the P0171 PONTIAC code detected? – Fuel injection system does not operate properly.
What does lean Bank 1 on a Pontiac mean?
P0171 PONTIAC Fuel Trim System Lean Bank 1: Code Meaning, Causes, Symptoms, & Tech Notes P0171 PONTIAC | Fuel Trim System Lean Bank 1 | The Engine Control Module (ECM) controls the air/fuel metering system in order to provide the best possible combination of driveability, fuel economy, and
What causes a p0171 fuel trim system Lean Bank 1?
If the problem persists the front oxygen (O2) sensor may need to be replaced. The P0171 code could also be caused may be caused by one or more of the following: debris on the MAF sensor causing an incorrect reading, improper oil level, low or high fuel pressure, or Engine Control Temperature (ECT) Sensor reading inaccurate.
What does the p0171 code in front oxygen sensor mean?
If the P0171 is combined with the P0174 code, it’s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persists the front oxygen (O2) sensor may need to be replaced.

How can I find out if my car has code p0172?
The first step in the diagnosis of a code P0172 and/or P0175 is to look at a minimum of three ranges of the Long Term Fuel Trim numbers on a scanner. Check the idle reading—3000 RPM unloaded and 3000 RPM with at least 50 percent load.
What does it mean when fuel trim is p0172?
Ideally, the Long Term Fuel Trim should be close to 1 to 2 percent. When a code P0172 is set, it means that the Fuel Trim is anywhere from -15 percent to as low as -30 percent compensated. When this happens, the computer knows that there is an improper condition in the control of the Fuel System.
What causes air flow code p0172 and p0175?
The fuel mixture grows rich and eventually, the code sets. An “over reporting” Mass Air Flow Sensor can be a common cause of a code P0172 and P0175. Essentially, this means that the Air Flow Sensor is telling the computer that much more air is entering the engine than actually is.
