Re: Replacing faulty CTS

EASY fix!



The CTS is about $20, the connector is about $25.



The connector comes with the wire splices. All you need is a crimping tool and a heat gun.



A crimping tool can be bought (a cheap one that will do the trick) for $10



A heat gun can be bought for about $30, but a cigarette lighter can be bought for 39¢.



Cut the wires, put them into the splices, crimp the splices and then heat them until the heat shrink tubing shrinks.



Then, if a code is set in the computer, you need to reset it.



Either use a code grabber to reset it, or do it the poor man's way: Disconnect the battery for 10 minutes.



Voila! Fixed.

LOL.....you can get a cheap one that will work about once(if you're lucky) at the dollar store :)

Please explain what the CTS is, having problems with my car and don't know what else to look for. I have replaced everything I know of.

TIA Jeff

Coolant Temperature Sensor.

It is a temperature sensor, about 1.5 inches long and about 1/3 of an inch in diameter.

It screws into the engine near the upper left (as viewed by the driver) side of the engine, and measures the temperature of the coolant.
