Coolant Sensor is too Low?TArider21 08-03-2004, 05:13 PM The service Engine Light came on in my car the other day, it is a 1992 camaro with a 3.1L V6, I scanned it and it said the coolant sensor is too low. Before this happened the car would not idle at any less than 1500rpm. I tried cleaning out the IAC motor, and now the engine will idle at 1000 rpm, but the check engine light is still on. Has anybody experienced a similar problem, and if so what was it? :confused: camaros_4_lfe 08-03-2004, 05:35 PM check your coolent???! and if its full its porb the sensor TArider21 08-03-2004, 05:39 PM I checked the coolant, and it is full, so it must be the sensor! Any more suggestions? :confused: HBHRacing 08-11-2004, 02:23 PM check the harrnes. could be coroded or lose. check for a 5 volt reffeence on one wire and a full ground on the other. if thats ok change the sensor TArider21 08-11-2004, 07:51 PM The coolant temperature sensor went bad, I replaced it, and it runs like a charm again! :metal: | ||
