Coolant thermistor

Engine block temp sensor is bad, or connection corrosion cause problems. Double check connections have bright metal. If not scrape with blade to bright (remove corrosion) still problem, change Sensor.

Low fuel light full

this car has the odd duck thermistor sensor
my guess, if the light is on full, and the tank really is full.
im logging in to to see, you can too.

the sensor is shorted, or the lt-green-red to it is grounding out to the body. just the opposite of the fuse #1 bad,
Fuse 1 is back up lights. so if it blow,, no backup lights.
no meter lights or no sunroof ops.

the test is easy, unplug the thermistor at tank
light goes out. key on, then the sensor is bad.
or some joker put the wrong light in the dash,,,,, too low wattage.

Location of heater / ac blower motor switch

well if it does have one it should be by the blower motor or behind glovebox but my best bet its ure thermistor its bad, assuming fuse and relays are fine, remotely think ure controls are bad.

2002 rover 75 cooling fan not working

The thermistor is possibly located closer to the engine. I would check the fan for power first. If the fan is receiving power, but won't turn then you are looking at the more likely possibility that the fan motor has failed. Moving components tend to fail more readily than non moving resistive types such as the thermistor.

My temp hand on the cluster wont moved i just got it fix and the company is saying it might be a temp swicth dats bad

That is correct. If your coolant temp. sensor is bad or there is a bad connection. Your temp. gage will not read the proper temp. The sensor is just a thermistor, here is what it looks like. You can check the sensor with an ohm meter. 10_2_2011_9_38_00_pm.jpg

Hello my check engine light is on i went to local parts house had them read the code low input voltage in the iat sensor so i bought a new one had the code cleared and before i left parking lot light was...

Keep in mind that the IAT (intake air temperature) sensor simply measures the temperature of air that is entering the engine. Intake air temperature is important because the higher the intake air, the higher the combustion temperatures. High combustion temperatures result in increased Nox (Nitrogen oxides) emissions. To keep these higher temps from causing increased combustion temps, the intake air tubing should be intact, allowing the engine to "breathe" air that isn't sampled from the engine compartment. The IAT measures air temp by using a thermistor, or a thermometer of sorts. The thermistor is supplied 5 volts reference voltage from the PCM (powertrain control module) and a ground. Usually, when the air temperature is cold the resistance in the thermistor is high and when the air temperature is warmer, the resistance decreases. This change in resistance changes the 5 V reference from the PCM, thereby informing the PCM of the temperature of incoming air. If the PCM notices that the incoming air temp is unusually high, say, 300 degrees, when the engine temp is still relatively low, it will set a P0112.

Symptoms: There may be no noticeable symptoms of a P0112 code other than an MIL (Malfunction Indicator Lamp). However, a emissions test may reveal higher Nox readings depending on the type of IAT failure. Or the engine may ping under load, depending on the type of IAT failure.

Causes: Usually the P0112 is caused by a bad IAT (internally shorted or open or otherwise damaged), but it could also be:
* No reference voltage to the IAT sensor due to an open wire
* Excessively high intake air temperatures
* Short to ground on signal circuit
* Damaged IAT connector
* Bad PCM

Possible Solutions:
Hook up your scan tool or code reader and read the IAT reading. With a cold engine, the IAT should roughly match the coolant reading, since both will read ambient temperature. If the IAT is reading excessively high, check the IAT connector for damage. If you find none, unplug the IAT sensor and recheck the reading. It should now read the minimum, around -20 deg. If it does, then replace the IAT sensor. But, if the reading is still high, unplug the sensor and check for resistance across the two wiring harness terminals. If there is infinite resistance, then the PCM itself is bad. If the resistance isn't infinite, then check and repair the short to ground on the signal circuit.

Keep us updated.

98 corolla drivers side window won't roll down or up well

I just repaired a 1999 Corolla (160,000 miles) window regulator with the same problem. I checked the motor commutator windings for shorts and the motor was OK. The brushes were still good. The motor is built like a clock - extremely well made with almost no indication of wear. Bench testing showed that the motor would not rotate once it had been run for a few seconds.
Elsewhere on the Internet someone mentioned a PTC Thermistor. This was exactly what was causing the problem. This is a special type of resistor "in series" with the motor that increases resistance when hot. It prevents the motor from drawing much current when stalled at the top or bottom of the window travel or in event of a jam, etc. The thermistor doesn't look like a standard "Radio Shack" part. By pulling off the motor top the magnets and commutator pull out. The PTC Thermistor is the two large copper plates separated by a silver looking material about 0.001" thick that are in series with one of the brushes. To fix, short out the thermistor. I tested with a small clip of copper wire. I made a permanent fix by soldering a jumper from one plate to another. During assembly, don't break the brushes.
The power window works great! I don't need an "electronic minder" to stop power to the motor at the top or bottom of the travel; I can do that. I don't intend to place my head in the window and push the button. If you have kids, this fix might not be for you.
