Where else could it have been on that donor motor? But on this one there is no CTS! The mount is there, but it hasn't been drilled out and tapped. I have checked and set the TPS and the Idle speed motor. Due to some changes to the idle speed set screw that you are not supposed to touch, (to get the car home), I opted for putting on a new, junker throttle body. On the engine I have, the CTS is on the passenger side of the throttle body. #2 Next problem is the ECU coolant temp sensor. I'd replace it and run a test wire to the instrument panel to see if it works. Dangerous practice if something goes wrong. Perhaps the sensor broke so the Previous Owner disconnected it. Could it be that the block had a temp gauge, but my Firefly doesn't? I have the dash gauge? How do I test this sensor? I put it in hot water (near boiling) and it still reads an open circuit, just as it did with open air. I have done everything but open up the main harness and look for it. I have the gauge sensor, but no wire to connect it with. #1 Right next to the rad fan switch, is the temperature gauge sensor, near the distributor. Where else could it have been on that donor motor? It has been over a year since I pulled that throttle body so I don't know what it was off of. Next problem is the ECU coolant temp sensor. Could it be that the block had a temp guage, but my Firefly doesn't? I have the dash guage? How do I test this sensor? I put it in hot water (neer boiling) and it still reads an open circuit, just as it did with open air. Right next to the rad fan switch, is the temperature gauge sensor, near the distributor. I was able to identify everything for this post. Thanks first to Starscream5000 for the engine removal pics. I have done a top end job and rings and pistons as the exhaust valves were burnt out. So I don't know much about the engine other than it was replaced from the original. My 95 has a 3 cyl engine, that from the looks of things was from a 96+. Time to blow the dust off of the work on the 95 Firefly.
