How to replace the coolant temperature sensor on a Saturn?

How to replace the coolant temperature sensor on a Saturn?

1 Park your vehicle in a safe location on even ground. 2 Locate the coolant temperature sensor in the hood area. 3 Identify the engine coolant temperature sensor as a black and copper-colored prong sticking out of the engine block. 4 Disconnect the sensor from the engine using a ratchet.

What should the temp of the coolant sensor be?

Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.

Can a bad coolant sensor cause a car to not start?

Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.

When to replace the temp sensor on your car?

The temperature sensor alerts the engine control computer when the engine is overheating. Replacing the temperature sensor is strongly recommended if you suspect the sensor is damaged. Park your vehicle in a safe location on even ground.

What to do if your Saturn has a p0128 code?

If cooling system is not leaking and the fluid level is OK, replacing the thermostat usually takes care of the problem. The cost to diagnose the P0128 SATURN code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.

When does a Saturn’s series engine fail?

The aftermarket replacements have a quality problem; best bet is to find a low mileage junkyard replacement or order the OE part (~$70). Not hugely common, but still a recurring failure. They usually fail when the engine is hot. You’ll be driving along, and suddenly the engine dies, and won’t restart until it cools.

What should the electrode diameter be on a Saturn s?

Without getting into too much detail, the basic requirement is the diameter of the electrode should be roughly the width of the ground. Most copper plugs fit this description. Narrow fine wire electrodes almost always cause problems, usually a p0300 and running like the car needs new plugs.

Why is my fuel pump not working on my Saturn s?

This is caused mainly by overdrawing from the 12v socket, or high power aftermarket accessories drawing from the same circuit. There will be melted plastic around the fuse. The radio, chime module, dome light, 12v socket, and fuel pump are on this circuit. You will probably know about it when the fuel pump stops working.
