Phantom "Check Engine" and "Overheat"

My 2001 Mitsu Montereo XLS is a great SUV...but it has a couple of problems. The Check Engine light comes on, and says the code for the air flow regulator - although all the sensors and the air flow value have been replaced. I understand that this model has some panel issues, and thought somehow this error could be part of that? The emmissons and all else check fine. It also says that it's overheating sporadically - my mechanic brother (heavy industrial Volvo, not Mitsubishi) use his temp reader, and while it was "overheating," the actual temp was normal and steady, even after it chose to "cool" back to it's normal temp on the gauge. Now, when you try to turn on the AC or heat, the fan motor will not work in positions 1,2 or 4. The AC light is engaged. When you turn it to 4 (highest) the AC light goes off, and the blower engages. Outside of shooting my beloved car - and I have to have it be dependable, it's the means of travel for myself and four children in a northern state (expecting snow, it's 4WD). Can you advise? I've paid so much money for "let's see if this works" and so far, it's only accumulating more phantom problems. btw - no real change in mileage, or preformance. It's a great car. Only recent change? Added headrest DVD's for our family vacation to see G'ma...good idea when you're driving 14 hours with little ones. It caused a fuse issue, was repaired, and went back to doing exactly what it did prior - dial says overheat, no AC blower on 2 or 3, and "check engine" is my near constant companion. Comes on about 5 minutes after they clear it. Help!

SOURCE: Code #P0171 & code #P0174

The most common problem on a Ford with these codes is deteriorated PCV hoses. Check the hoses from the PCV valve to the intake manifold. Pay special attention to the rubber elbows. They often crack on the inside curve and the crack is hard to see.

Sounds like you are either low on coolant, or a head gasket failure.

SOURCE: 2001 chevy monte carlo is overheating when driving

If your engine cools down when moving fast, you either have a problem with your water pump or your electric fans that cool off your radiator and a/c condenser. This is controlled by a temperature switch, but these fans should kick on instantly when A/C is selected.

I have a 2001 Mitsubishi montero sport xls model. My check engine light is on and I have a code number of P0715...does anyone know what that code means?

The code indicates the Input Turbine shaft speed sensor is giving an erratic signal or there may be a mechanical transmission issue. I would go with a new sensor. Try to purchase a new sensor, much cheaper than the dealer. Also see sketch of location of the sensor on the tranny.

2001 Mitsubishi Montero XLS with 110K...check engine soon light came on while sitting idle ...IS THIS A CONCERN? CAR RUNS AS NORMAL

the computer is sensing something is wrong. If running normal, dont worry about it. Check your gas cap, cross threading it is a common "check engine".These lights are also called dummy lights. They are very sensetive.

2001 mitsu galant 6 clynder service soon ingine light keep on co

i would start by taking it to autozone and having them read the trouble codes that are in your car. they offer this service for free. You can then go ahead and fix the problems. It could just simply be that you did not put the gas cap on all the way the last time that you filled up the tank.

2001 300m overheating problem.

When the vehicle overheats, do u check the water/coolant level in the radiator? If it has reduced, it means ur leaking and u should inpsect to c where the leak is coming from. If the level has remained the same, probably ports are blocked or something to that effect. Keep me posted though
