Question about 1996 GMC Sierra

2 Answers

1996 GMC Sierra 1500 P0174, P0171,P0154, AND P0122

My truck is showing all of these codes. Can one of them cause the rest to show up or is there something that can cause all of this? someone told me it could be the mass air sensor but I want some more input before spending 150.00 for the part.

Tim,

Yes these codes are associated with the MAF Sensor. One can trip the others as well. I would try removing the MAF Sensor and cleaning it first (brake cleaner or contact cleaner), then if that doesnt work I'd chalk up the bucks for a new sensor. Check this link for additional info on this http://www.obd-codes.com/p0174

Sincerely,

JC

2001 GMC SIERRA 1500 4X4 CODES P0171 AND P0174 CHECK ENGINE LIGHT IS ON WONT PASS EMISION


Sometimes this is NOT a O/2 sensor issue ,,,,,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 persist 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 MAF sensor causing an incorrect reading, improper oil level, low or high fuel pressure or Engine Control Temperature (ECT) Sensor reading inaccurate,,,,,

2004 x-type 3.0 v6 152,000 miles showed codes P0171, P0174, P2096, P2098, P0101, P0171 pd, P1000.


check for vacuum leaks or a faulty mass air flow sensor. all the codes have to do with engine too lean(too much air).

Check for vacuum leaks to start. Then check the evap system. I just replaced a evap vent solenoid on a suburban with the same codes. fixed the problem.

2002 GMC sierra system too lean(bank 2). Code P0174.


Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 2 is generally the side of the engine that doesn't have cylinder #1.

Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.

Symptoms: 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: A code P0174 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 can 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 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


Hope this helps (remember to rate this answer).

P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks. P0174 OBD-II Trouble Code


Technical Description

System Too Lean (Bank 2)


What does that mean?

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.

Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.
