How many Engine Coolant Temperature Sensors are on the 1992 Ford 2.3L Ranger and where are they located?

This vehicle has excessive miles and the coolant sensors have never been changed. The vehicle is having driveabiltiy problems such as a %26quot;lean%26quot; miss which seems to occur about 75% of the time. The %26quot;check engine%26quot; light is on but I have the EGR Valve blocked off at the throttle body; thinking earlier that it was causing the %26quot;LEAN%26quot; problem...it wasn't responsible...no improvement since that alteration.How many Engine Coolant Temperature Sensors are on the 1992 Ford 2.3L Ranger and where are they located?
There is one on the drivers side of the cylinder head, about midway between the front and back of the engine. Make sure you don't have any vacuum leaks (especially the brake booster).

Usually if the temp sensor goes bad, it causes an overly rich condition, but it's possible that it could make it run lean.How many Engine Coolant Temperature Sensors are on the 1992 Ford 2.3L Ranger and where are they located?
i know one is located on electric fan, but for others im not sure. hope this helps.How many Engine Coolant Temperature Sensors are on the 1992 Ford 2.3L Ranger and where are they located?
temp sensor for the computer is located top of engine near thermostat housing

there is a sensor for the gauge too.

radiator cooling sensor or switch.

you might check the pcv and while your at the throttle body check the iac. clean all connections corrosion is a possibilityHow many Engine Coolant Temperature Sensors are on the 1992 Ford 2.3L Ranger and where are they located?
2. one on the head passenger side below radiator hose. one middle ways on block on passenger sideHow many Engine Coolant Temperature Sensors are on the 1992 Ford 2.3L Ranger and where are they located?
On those things, I wouldn't worry about the ECT causing your problems as I would the ACT and the B/MAP...





ACT is a air charge Temp sensor that measures intake air temperature and get caked with oil over the miles.



The B/Map measures the Barometric pressure (altitiude) and intake Vacuum pressure while running.. IF it screws up, both will casue headaches.





But I had a miss in a 89 ranger with a 2.3 that came to be a set of bad plug wires, and a cut wire going to the crank position sensor..



Check all of those things first.. But please post the codes next time...



If you don't know how to retreive, look up reading codes on a EEC IV vehicle.How many Engine Coolant Temperature Sensors are on the 1992 Ford 2.3L Ranger and where are they located?
I'd reconnect the EGR. Clear the PCM memory by disconnecting the battery for 30 or more seconds, and then let the PCM tell you exactly what is wrong with your car.



These cars had OBD-I, which are not as complete as OBD-II introduced in 1996. But they still will detect and indicate if, for instance, your ect or act sensor is open or short.



OBD-I also had on demand diagnostics that actually ran a suite of tests, like open and short circuits, at idle.



You can actually run the on demand test by shorting a certain wire, and read the %26quot;codes%26quot; on your instrument panel which blinks out a code. it is easier with an OBD-I scan tool, which now, so many years later, you might be able to pick up cheap on E-Bay.



To see how I'd search the web for %26quot;OBD-I Ford%26quot;. You can also find out this is some Chiltons type literature. Its been too long for me to give you the details but I know it was possible.
