supplybfk Posted September 24, 2009 Share Posted September 24, 2009 The check eng light came on, and I pulled a p0116 (ect sensor circuit) code, reset the light, and it hasn't come back on. So I've tested the fan by giving it direct battery power and it tested good. I backed probed the fan module wires and they were good. The water pump isn't howling. The coolant level was fine, and both hoses were hot so I assumed that the thermostat is opening. The fans, however don't come on. Would it be either the ect switch or the ect sensor a combination of both? Thanks. Quote Link to comment Share on other sites More sharing options...
