SOURCE: Cleaning the Mass Air Flow Sensor

i will try to help. 171/174 indicates lean condition in engine. the mass air flow sensor is located in the rubber tube going to throttlebody. you can try to clean it. using mild carb cleaner safe for sensors, remove sensor from tube. spray clean the tiny wires located in the cylinder. do not touch them, they are very delicate. these engines are also notorious for leaking intake gaskets and faulty pcv valves. these will all set these 2 codes. feel free with anymore questions.

SOURCE: MASS AIR FLOW SENSOR REPLACEMENT & DIAGRAMS

Very easy for the Mass Air Flow Sensor....it is in the duct between the throttle body and the air filter box. Just unclamp the tube and remove the old and replace with the new.

SOURCE: 98 chevy suburban, code reads mass air flow sensor

Check the wire leads and clean them before reconnecting the wire leads. It wouldn't hurt also to clean the MAF sensor with MAF cleaner, the code your getting is most common to the high performance oil base filters like K&N.

Good luck and this should help you resolve your MAF issues. Thank you for using Fixya

SOURCE: rEPLACING mass air flow sensor

The mass flow sensor on the 1999 intrigue is along the intake tube right after the air filter intake housing. Loosen the two clamps that hold the MAF sensor between the Air filter box cover and air intake tube, disconnect the wire leads at the MAF sensor connection and remove the MAF. Note it's uncommon for the MAF sensor to go bad and 95% of the time, cleaning it with MAF sensor with MAF cleaner will fix any problem it may of had to trigger the DTC codes.
Start with trying to clean it first just by following the instruction on the MAF cleaner. This should save you time and money to get your Intrigue running 100% again soon.
Good luck and thank you for using Fixya.

My 2004 yukon would start then die i replaced the fuel filter and it will turn over but wont start the fuel pump is working what could be the problem

Mass air flow meter, crank position sensor, Water temp sensor all affect starting problems. Have a diagnostic test done on it to reveal any codes that come up that will pinpoint the parts causing the problem.

Where is iat sensor located on 2006 tpyota tacoma 4,ol ?

Intake Air Temperature (IAT) sensor and Manifold Absolute Pressure (MAP) sensor are combined into a single assembly which is called Mass Air Flow (MAF) sensor. This MAF sensor is located on the air filter box near air filter hose, and is connected with a five wire connector. You cannot replace the IAT sensor alone. Instead a MAF sensor is replaced altogether.

2004 avalanche. no start, codes po102 and p0442. fuel pressure within specs

With key off unplug the mass air flow sensor and try to start the vehicle. If it starts and runs fine, try cleaning it with mass air sensor cleaner, and plugging it back in. If cleaning doesn't solve the problem it may need replaced.

My 2004 toyota tacoma has a rough idling problems and I was told to replace MAP sensor. Now, would it be Mass air flow sensor ? Because I can not locate any info on MAP sensor of this yeat truck

Yes your truck is equipped with a mass airflow sensor (MAF). However, I would not just replace that because its running rough. I would begin diagnostics by first checking to see if there were any trouble codes in the engine to give you a clue as to the rough running condition. I would expect a trouble code to be present to support the descision to replace the MAF Sensor. If no codes are present I would suggest that you get the vehicle tuned up. (Spark plug replacement and throttle body cleaning and I would also suggest removing the idle control valve and cleaning the carbon and dirt out of it. Although what you were told might be correct I dont belive that is where I would start.

2001 Tacoma running rich but the scanner is reading a lean code

No, disconnecting the sensor and seeing no change would be a indication the maf was bad. Your computer takes information from your mass air flow sensor (maf), o2 sensor, cam position, and knock sensor to regulate the correct mixture. I would suspect a bad o2 sensor upstream. Try taking off the o2 sensor and seeing if there is black carbon on the base of the o2 sensor. If it has black carbon on the base it could be a bad o2 sensor. This problem could also be easily solved by hooking up a mechanics diagnostic computer to pin point the problem. Sometimes, you can clean the mass air flow with a special cleaner to help it generate a more accurate reading.
