Is there a way to get the codes out of a 93 saturn 4 door sedan without plugging in? I don't have a plug with my scanner that will fit,.I think it needs a coolant temp sensor,it idles high and the fan comes on as soon as its cranked and its cold.....now it turns over about a minute before it cranks and is hard to start....like a throttle pos sensor.the check engine light isn't on and I don't wanna start throwing parts on it without checking first....any help will be appreciated
With the key OFF, pull the cooling fan relay, and tap it vigorously on your knuckles. Now plug it back in, and turn the key to ON, but do not start the car. If you hear a click from the relay, and the fan starts, best chance is that the temp sensor is shorted, and needs replacing. Verify this by turning the key to OFF, disconnecting the temp sensor connector, and measure the resistance of the temp sensor. Zero ohms signals a bad sensor.
