Before you do anything, try removing the battery cable for a couple of minutes and then reinstalling it. This will clear the faults in the ECU. If the code comes up again, then you'll need to check your wiring.

What else could cause the check engine code to read mass airflow sensor?

OBD Codes have nothing to do with telling you the
problem or the need to replace parts

Codes are used to diagnose the system with the fault,
that set the codes

Have to component test the entire vehicle system, to find a

You were only told about the code

No one can tell you what the problems may be, until the vehicle
is properly tested to even find a problem

Why does my car idle ruff

Hard to says without more info... Do you have a check engine light on ever? If so get that code read and you'll have a much better idea of what's wrong...

If you don't have a check engine light that's on you might want to check for a vacuum hose that's leaking, but if not there's probably a bad sensor or valve needing replacement.

Code 157

Error code 157 on your vehicle indicates a problem with your mass airflow sensor. The mass airflow sensor gives a reading based on the air intake and output within the engine compartment. A properly functioning sensor will contribute to better fuel economy. In some instances, you may be able to clean your mass airflow sensor to clear the error code, but the error will most likely return in a short time. Fortunately, replacing the mass airflow sensor is a reasonably simple repair.

Backfires on cold engine start,then goes away as it warms up.

the ECT sensor for the computer could be giving the computer a false temp reading and causing it to happen also..thats why it runs good warmed up... if this does not work, clean or replace mass airflow sensor. good-day ! ECT- engine coolant temperature sensor,

Replaced mass airflow sensor in 2001 tacoma twice. Is their a way to clean, bypass, etc. new unit lasts about two months, ie engine light comes back on and mechanic is ready to replace sensor, clean...

If the new unit only lasted a couple of months, and the engine light goes back on, I think that you should try to have it replaced at the auto parts store under their 90 day warranty policy, if they have that.

Try to go to a reputable source such as Autozone or Advance Auto Parts where they have a more liberal return and refund policy.

Usually, a MAF sensor once replaced shouldn't go bad in such a short time span.

Maybe, check that the voltage to the MAF sensor is not too much for the sensor, causing it to go bad. If that's the case, the computer reference signal voltage may be the culprit.

Good luck on this repair.

My 2001 ford taurus with the standard V6 engine (200,000 miles) has alot of trouble starting... The battery is just 2 months old, and the mass airflow sensor, timing sensor, and starter have been...

check compression on each cylinder and fuel pressure,I dont know if you have the tools,but for that engine whit 200,000 miles,I think the compression is down,at least you got to have 75 of compression on each cylinder.

I I have a 2001 ford expeditionit feels like a misfire.i just replaced all spark plugs and cleaned maf ar PO113PO118and PO102.Thanks.

Replace the coolant sensor,and make sure there is enough coolant in the system,and the mass air flow is most likely bad,but replace the coolant sensor first,cause the circuit is the same,sort of,it has to be in check for the reading of the mass air flow can be detected,so replace it first,it is the cheapest also,after changing the coolant sensor,you may not need to replace mass airflow sensor,but the mass air flow is not working,but like I said the coolant sensor needs to be replaced to make sure of this.

2001 ford taurus with check engine light on. code

Make sure you replaced the right one there are two sensor's for the coolant, one takes coolant temp and the other one runs the fans for the radiator. Both are located on drivers side of the block. 2 wire leads on each how ever both are different in sending readings to the computer.Both look just alike also. Just make sure you replaced the right one. Or replace both.
