I will check those 2 sensors. I found a pin-out diagram online for the ECM connector and if I can trust it, it looks like everything is basically the same for the 4.9, 5.0, and 5.8 except for the number of injectors and a few wire color differences from 92-93.
The PCM connector is the same for V8 versus 6 cylinder engines. There will be differences for transmission as well as later model changes for Speed Density versus MAF. The place where things frequently change is connector C101.
C101 is a big connector located on the driver side inner fender.
And that's the one I do not have a pin-out diagram for. There may not be any differences between a V8 versus 4.9L engine for that connector, but then again...there might.Most likely given everything works you are fine.
I checked the 2 sensors. The CTS checked fine. Ended up at .64V and 2.62 K Ohms after engine was warm. The ACT is at 32.5 K Ohms at 68 deg. (within the 15%). With the engine warm it was at 1.4V and 5.3 K Ohms, however, I do not know the temp of the manifold. Both have 5 volt supply.
I haven't found the diagram for a F150/ I did find this. Its from a 94 Bronco. I know it could be different for a 92, but it appears all engines use same connector.
That's the caveat here. From year to year the circuit/function can move to different pins. A 1994 Bronco is most likely MAF and more than likely there are a few pins that have different functions assigned to them than a 1992.
There may be no issue with the pin-outs for C101 on your truck, it's just something else to keep in mind. Your ECT and ACT sensor values look reasonable.I would pull out the computer for an inspection as a next step. Also make note of the alpha-numerics on the computer. Specifically the Ford engineering number (example F4ZF-12A650-EA) and the programming code (example HOG0). Could be a mismatch for your engine.More info here: Fuel Injection Technical Library » EEC Program Codes
