will this actually show the temperature of the engine oil like 200 degrees,i would like the numbers not a gauge reading

I don't believe the Ranger has a sensor for engine oil temps, thus there is no monitor that will bring it up.
There has to be some type of sensor for any monitor to read.
I have a ScanGauge lll that can read just about all the sensors on the Ranger. but, alas, no engine oil temp.
There is however a transmission fluid temp and a coolant temp which I have on first screen of the ScanGauge.

Totally agree.

New question: if you added a temp sensor (from some Ford product that has one) to the oil pan or some kind of oil filter adapter, how would you get that signal into OBDII feed??
@airline tech ... your thoughts...

You are correct. I actually had to check my scan gauge because I thought it was on there.

I don't think any Ford has a sensor for oil temperature. Oil pressure, possibly, but not temp.
Have to ask tho.....why the need for oil temp ??? I would be more concerned with the trans and coolant temps and those are readily available to access on several apps and ScanGuages.
Bit of searching indicates normal engine oil temps are in the 230 to 260 degree range, with synthetics able to withstand almost 300 degrees.
I would think that if the engine oil ever got to the point of overheating, the coolant and trans would have already failed....engine and tranny would have gone kuput !!!

Although the PCM has an available code that can be generated, there is not a actual - Oil Temp Sensor.

DTC	Description	Fault Trigger Condition
PCM P0298:00	Engine Oil Overtemperature Condition: No Sub Type Information	Sets when PCM detects the engine oil temperature protection strategy in the PCM has been activated. This temporarily prohibits high engine speed operation by disabling injectors, to reduce the risk of engine damage from high engine oil temperature. The PCM uses an oil algorithm to determine actual engine oil temperature.The engine is operating in high RPM range due to incorrect gear selection. This may cause a lack/loss of power or surge.

• NOTE: The PCM uses an oil algorithm to infer actual temperature based on input from the engine temperature sensor.

So, since there is not a sensor there is not a PID display for it that I know of, however I can try hooking up my scan tools to see if I can view the (Inferred Oil Temp), I do not recall seeing it anytime I have been hooked up.

Would have to research if there is an available port where someone could install a sensor and then run a power and ground feeding a gauge in the dash, as anything for PCM PID would have to program the PCM to generate the sensor input into the PCM out to a digital display.
I THINK someone on here has installed one and ran outside of the PCM, it can be done if we can find a spot to install a sensor that would give a correct reading.

In general, I agree. Oil temp is not a critical measurement if overall engine temp (coolant) is in normal range. It was more a curiosity question. Like the aftermarket aluminum trans pans having a boss (if drilled and taped) to accept a sensor (temp, level, whatever you have in mind) how does one add that into the OBDII feed as opposed to a standalone gauge??

As I watch "I Do Cars" YT channel where he tears down blown engines each week to see why they failed, and the number of ceased engines with spun bearings where things got HOT (and likely no) oil is surprising. Having an oil temp might give a early warning at things are not as they should be. I would imaging the GM L87 engines that are on massive recall would benefit from that.

PS: after looking around, Ford does have direct oil temp sensors but mostly for the diesel engines. LOL, they also list one for the Focus and Transit but the location is for ambient air temp up by the radiator. (engine oil temperature sender )

OBDII specs does have a PID for oil temp sensors:

PID (Hex)	PID (Dec)	Data bytes returned	Description	Min Value	Max Value	Units	Formula[a]
5C	92	1	Engine oil Temp	-40	210	°C	A-40

Not sure if temp sensors are one wire or two wire devices (guessing 2... -/+... the hotter the more the resistance... do not know if a signal wire is needed). In either case, does/is there a pin/port/connector in the PCM (even the ECU??) to hook the sensor wires up to?? As OBDII has mandator "things" all manufactures HAVE to implement and a section that is optional and defined by individual manufactures, I don't know if oil temp is mandatory or optional. If mandatory, would hope no real programing would be required(???). If it gets a signal it displays. If optional, then not so much.

Yes - the OBDII offers a Oil Temp PID but it is not a required PID, and the Ranger is not programed for it.
I checked with 3 scan tools and the only PID's related to Oil Temperature are:
Start/Stop Disabled - due to oil temp High, so this would be the (Inferred Oil Temp) from the ECT Sensor.
No PID found for that - Inferred Temp Reading
I checked both Ford Specific by VIN and EOBD (Generic Data)

If the Ranger had a Oil Temp Sensor installed we would have a PID to display the data, since the main (Input) data for the PCM for temp utilizes the other temp sensors for input data there is not really a true need for oil temp as a input, mainly if the Oil Temp is high, then the engine temp will also be high.

ok thanks everybody,i think i read that usually whatever the coolant temperature is the oil temperature should be about the same
i was just asking because i had a 2024 chevrolet colorado 2.7 that showed engine oil temperature
