Question about 2002 Chrysler PT Cruiser
Check the ground connections (black wires) attached to the car's sheet metal under the hood and near the main computer (wherever it is located). Bad ground connections (loose, rusty, etc.) can sometimes cause problems like these.
If that doesn't work, use a voltmeter to determine if power is being supplied to the sensors when the ignition is turned on.
--If yes, it's either a problem with the wiring/connections from the sensors back to the main computer, or a problem with the computer itself (somewhat unlikely).
--If no, either buy a repair manual for your specific year/model or visit a model-specific forum and see if you can find a wiring diagram. That should tell you where the power to the sensors is supposed to be coming from -- the computer or another source. Tracing those wires/connections will hopefully identify the problem.

Hi, i have put together a step by step guide that will help you with this replacement job. Make sure the vehicle is in a cool state before starting this job.
* Drain some coolant into a clean container until the coolant level is below the thermostat housing.
* Remove the upper radiator hose connection from the thermostat housing.
* Loosen the housing bolts and remove the housing.
* Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
* Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
* The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
* When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
* Install the gasket.
* Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
* When the engine has reached operating temperature make sure the thermostat opens.
* You should be able to see coolant circulating within the radiator.
* Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
* If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.
When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step.

Check the wire harness, make sure there are no breaks or crushed wires. Also check the wire harness to the TCM, look for any loose connections. Good luck and keep me posted. Be glad to help.

The input speed sensor is just under$30.00 at the dealer and it should take you less time to replace it then to find it. The sensor is on the transmission under the battery tray closes to the engine. There are two sensors and the other one is the vehicle velocity sensor which is the one furthest from the engine block. Your going to need a 1' socket to remove the sensor and extension and a swivel. Find the solenoid pack connector on the transmission which is under the battery tray and right above that should be the input sensor. Un-clip the wire lead to the sensor and remove the sensor, install new sensor and re-clip the wire lead and re-install anything you need to remove to get to the sensor. Good luck and keep me posted, it may be easier to go from the bottom of the cruiser.
