Will the MAF sensor cause the vehicle not to start 2002 Buick Rondzviue

Hi Laurena,

Was the car turning over before the MAF sensor was replaced? I'm assuming it was.

Is the MAF sensor you replaced it with a Genuine GM part, or is it an aftermarket part? If it's aftermarket, it's likely to cause starting and driveability problems, and should be replaced with an OE unit.

It's also possible that the process of changing the MAF sensor has either shorted something out or caused an issue with the connection of a power/ground somewhere that feeds the circuit in one of the components needed to start the car (fuel, air, spark etc).

MAF sensor trouble code P0102 caused by bad ground GM 3100
Repair Buick LeSabre P0102 MAF Trouble Test it if you have the tools an you know how .

You have a MAF and MAP, The mass air flow signal varies with engine load.It is attatched to throttle body. This if it is the primary signal can cause the problem you desribe try and disconnect it and see if it idles properly. The next item you need to inspect is the MAP ,manifold air pressure this is a back up for the MAF sensor.If this sensor fails you will not accelerate correctly and stall out flooding the vehicle with fuel. This monitor the MAF and your EGR. If the EGR valve is stuck open the vehicle stumble and stall out and affect the performance of the MAF and MAP.Make sure your MAP is connected and the vacuum hose is attatch this item is located at top rear engine compartment near fuel injectors

Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0103, and P0104.

Symptoms: You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes: A code P0102 may mean that one or more of the following has happened:
The MAF may be disconnected, or a wiring connection may be bad
The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
The MAF sensor may be faulty
The vehicle computer may be faulty (very rare)

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.
Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
Replace the MAF sensor.

P0100 - Mass Air Flow (MAF) Circuit Malfunction

Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. Other MAF sensor circuit DTC trouble codes are P0101, P0102, P0103, and P0104.

Symptoms:
You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes: A code P0100 may mean that one or more of the following has happened:
* The MAF may be disconnected, or a wiring connection may be bad
* The MAF sensor may be faulty

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
* Unplug and reconnect the MAF wiring harness
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
* Replace the MAF sensor

Then, like a reference guide check this TSB DTC P0102 MAF and this article about Mass Air Flow sensor, what does it do and how it does it.
Test, check it and keep us updated.

The PCM controls the air/fuel metering system to good overall fuel economy, driveability, and emission control. During open loop, the PCM determines fuel delivery based on sensor signals, without the oxygen sensor input. During closed loop, the PCM adds oxygen sensor inputs to calculate Short and Long term fuel trim fuel delivery adjustments. Short Term fuel trim values change rapidly in response to changes in the oxygen sensor signals. Long Term fuel trim makes coarse adjustments in order to maintain an air/fuel ratio of 14.7:1.

Possible Causes:

• Air leaks in intake manifold, exhaust pipes or exhaust manifold
  
• Fuel control sensor is out of calibration (ECT, IAT or MAF)
  
• Low fuel pressure (fuel filter clogged, pressure regulator failure)
  
• One or more injectors restricted or pressure regulator has failed
  
• HO2S element is contaminated, deteriorated or has failed
  
• Vacuum hose is disconnected, broken, leaking or loose
  

Troubleshooting:2002 Buick Park Avenue, 3.8L, P0171

Have you had a diagnostic scan ran? It sounds like you may be having a problem with the MAF sensor. The MAF regulates the amount of air taken into the car. The sensor responds to the engine temperature.

remove maf sensor and check for air filter debris on it, gently blow off debris taking care not to damamge the wires on the sensor. also check forvaccum leaks as this can cause a lean condition

P0102 - Mass Air Flow (MAF) Sensor Circuit Low Frequency, clean inside the of MAF sensor with spray brake clean, if code returns replace the Mass Airflow sensor (MAF)
P0440 - Evaporative Emission (EVAP) System,
poss loose or leaking gas cap
P0128 - Coolant Thermostat Below Thermostat Regulating Temperature,
replace the thermostat, engine running cold
P0716 - Input Speed Sensor Circuit Intermittent, this is a problem with the VSS, vehicle speed sensor, replace it.
Clear all the codes after above repairs and drive a few days, then retest system for codes.
