I have just about given up on this truck and forum... It seems like I can not find the fix for my problem. So I figure one last shot would be to replace all the sensors, and if nothing changes, I'll drive the truck across the scales.

Can anyone give me a list of all the sensors on a 2004 Ford Ranger 3.0 Engine and 5R55E transmission?

 

It will not solve your problem, whatever that is, but I will list them

Transmission
DTR(digital transmission range) sensor
TSS(turbine speed sensor)
TFT(trans fluid temp) sensor
ISS(intermediate shaft speed) sensor
OSS(output shaft speed) sensor

Engine
CKP(crank position) sensor
CPS(cam position sensor)
MAF(mass air flow) sensor
ACT(air temp) sensor<<MAF and ACT are together
ECT(engine coolant temp) sensor
Knock sensor
TPS(throttle position sensor)
Fuel tank pressure sensor
O2 sensor B1S1
O2 sensor B2S1
O2 sensor B1S2
O2 sensor B2S2(dual exhaust only)

All these are tested after startup and then every few seconds while vehicle is running, computer WILL set a code if there is a problem.
Computers can start to fail, very rare but can happen, easy test is to unplug a sensor and see if computer sets a code for that sensors wiring

Nothing "they" add to the outside of a gasoline engine changes how it works
Computer and sensors were added to make engines more reliable and more efficient, and they do.

Fuel
Spark
Compression
That's all there is to it
Engine will run poorly if there is a problem with one of these.


Automatic transmissions run on Pressure, always have
Pre-computer Valve body would have pressure build up and it would "shift gears", or pressure drop and it would "shift gears"
Sensors and solenoids allows for better shifting, less wear on clutches and brakes(bands), smoother shifting as well, also better MPG because it can react to engine RPMs faster

 

Thank you. I am going to replace all the sensors, if the problem continues, I'll put the old parts back on, and watch it be crushed.

 

*** UPDATE ***

​​​​​​A family friend spent about 15 minutes combined, under the hood, asking questions and test driving it. He said it's an issue with exhaust. Suggested I look at the 3rd catalytic converter. I pulled it out, and Wow! My whole problem. It now has too much power for the old U joints.
