Most air temp sensors are on the air duct from the filter box to the throttle body.

I unplug the Air Temp Sensor to remove Air Box, when I put everything back together the check engine light came on. just unplug and replug.


Probably the ECM just needs to be re set. There are several ways to do this. One way is to disconnect the Negative battery cable from the battery for about 3 minutes, but there may be a risk of having the security system go off , and there is a possibility of stored radio info being lost. So I think Auto Zone and Advance Auto can use their scan tool to reset the ecm. I don't think they cgarge anyting...

Gas mileage is terrible,check engine light on,put on computer by friend said o2 sensor -i wasnt sure my friend new what he was doing so took to auto zone now they say the computer wont read


auto zone reader will sometimes not read codes. take it to your local garage and ask them to plug into it with an updated reader. i dont charge to read a code and i would hope they dont either. the o2 sensor could cause bad gas mileage. whens the last tune up done? check air filter. plugs? also check air in tires. low tires can cost fuel mileage as well. hope this helps

Problem Temp of the galloper 2001


Please be as specific and give as many details as you can. The antifreeze should take around 20minutes to come to running temperature. And running temperature should be between 190 to 210 degrees.
If Your car has become a fuel guzzler you will need to find out why. Gather as muck info as you can. How does the car start? Does smoke come out of the exhaust at an idle or at high idle? And if so what color is the smoke? Does the car idle uneven or rough? Is the engine light on and if so have you had the codes read? Auto-zone will do it for free. Is this car turbo charged? A defective turbo or air-leak, clogged air-filter, defective EGR valve, bad fuel-injector, or bad motor oil can cause poor mileage. I would like to help you but I need more information. Please let me know and good luck.

Bmw trouble code P1624 what does it mean?


Code P1624:M52 coolant temperature below thermostat regulating temperature. Check the temperature of the coolant and also with a scan tool, check the actual reading given by the coolant temperature switch. It could be the thermostat or a coolant sensor.Look also for any broken/corroded wires to the sensors as well.

My sons radiator hose busted. It has been replaced and refilled with antifreeze. Runs fine, still burning off antifreeze that got onto the motor. The temperature is running good but the "low coolant" light...


Could be just the coolant has gotten onto the water temp sensor and is causing it to ground out,,,this may clear up when it dry's completely.
If not,,then the temp sensor may be stuck in the grounded position, and may need replacement.

Air conditioning


On a w body car with a single temp adjustment control (not a dual zone) your problem should be a low refrigerant charge. Due to the design of this evaporator, a low refrigerant charge will cause the furthest areas from the inlet and outlet hoses (the drivers side) to not remove the heat from the incoming air. This allows the air on the drivers side to be outside temp but refrigerated on the passenger side. In cars with Dual Zone controls you must not only verify the refrigerant charge level, but also check the mode doors which control the air flow and regulate the temp. To check the refrigerant level do not use pressure gauges alone. Verify a proper charge level by checking the temperature of the two aluminum lines going in to the firewall of the vehicle. With the A/C set to high the temperatures should be within 5 degrees of each other. If not, then there is a charge issue. I hope this helps
