Question about 2001 Chevrolet Monte Carlo
If the temp outside is 40 degree F - the temp gauge sticks. The check engine light kicks on after driving like that in about 15 miles. Code reads to Temp sensor - How do you replace. Purchased part, but cannot find where Temp Sensor is located? anything I need to know about changing it?
Yadayada ,don't know where you came up with that . This vehicle has just one ECT - engine coolat temp. sensor . It's an input for the PCM - engine computer . The PCM sends this info to the instrument cluster over the class2 serial data bus. . The proper way to diagnose a problem like this would be to hook up a professional scanner an check input data to the PCM , an instrument cluster . Not guessing an replacing parts .
Engine Coolant Temperature Gage
The IPC displays the engine coolant temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine coolant temperature. The engine coolant temperature gage defaults to 60°C (140°F) or below if:
• The PCM detects a malfunction in the engine coolant temperature sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.
What engine ? could have come with a 3.4 or 3.8 L .
Engine Coolant Temperature (ECT) Sensor (L36)
Left side of the engine, below the thermostat outlet
Engine Coolant Temperature (ECT) Sensor (LA1)
LH side, top of the engine
Both are close to the thermostat housing , do you know what an where that is ? Follow the top radiator hose to the engine , should be near there . Look at the new part ,can't you match it up.

SOURCE: Temp Sensor
The temp sensor known as the engine coolant temp. sensor tells the computer if the engine is overheating and so forth and tells the injectors how much fuel to give the engine. The temp. sending unit is what controls what your guage reads. It sounds like you need the temp. sending unit. It located near the thermostat housing with a single pole connector.

the sensor is in behind the nosecone. but this should not effect the ac system . it would it the inside temp sender said that in the auto mode only. put it in defrost mode and the compressor should be on if not you have another problem (maybe low on freon)

The outside temp sensor is located in front of the radiator at the bottom of the radiator....It should have a two wire harness pluged into it.

The sender is on the driver side cylinder head between cylinders 1 and 3. The single wire connector to the sender gets very brittle over time from being subjected to heat from the exhaust manifold. It's somewhat common for them to break. Give that a look as well as the wire to it.
