Truck is in Limp mode

[Zranger20]

Started my ranger this morning and this is what’s happening. Truck is idling very rough, trac light is on, CEL is on, wrench came in and vehicle is in limp mode, can’t go past 10-15mph tax is bouncing around the 1K range. Currently don’t have a code reader on me. Any idea what could be going on?

That is a wide array of errors. Other than looking for a wiring harness that has been chewed by rodents, I'm at a loss.

I’ll rule out the rodents for now, I haven’t seen any indications of rodents in my garage or under the hood. Maybe a stuck open throttle body?

I know it sounds dumb.... But have you tried disconnecting the battery and reconnecting it?

If it's a fluke, it'll go away and stay away... If not, it'll come right back...

Not yet, I’m like out in town and didn’t have any tools in my truck since I just bought it. Has 55k miles on it so warranty is donezo

Powetrain warranty is 60k, no?

So you're driving the truck around like that?

You're ruling out mice damage because you've seen none, yet you just bought the truck? Do you not think it's possible it happened before you bought it?

You have a throttle body issue According to your app. You could swap the tps to test it. Or look for broken wires there. I second disconnecting the battery for a bit.

Additionally try calibrating you throttle body. There is a KOEO method to do it.

Not driving the truck like that before I figure out what’s wrong with it. Could be possible it had rodents before I bought it, I’ll have to look under the hood to confirm. Had the truck for almost a month before the lights came on this morning

You have anything plugged into your obd2 port?

The same problems SOLVED: Ranger Went Into Limp Mode, Engine is Only Running on 3 Cylinders. down below messages........... or the link.....good luck

Was able to pull code P2112 “throttle body plate is stuck closed” I’m guessing it probably got frozen?

One of the Rare signs of Low Battery Voltage - check to see if above 12.2 Volts
Plus clean your parking sensors, looks like you have snow on ground - Possibility?
Try cycling Tracking Control - Off and Parking Assist - Off
Check the Intake Tubes for Loose Clamps, Splits
Check Plug Wire - Connections
These are quick things to check without hooking up scanner for the codes

Good, sounded like you were driving it around.

Mice damage COULD take a while to manifest a problem.

Here is the Pinpoint Test for it, if resetting does not fix it
Plus clean the throttle plate with some carb cleaner & pull and reseat the connector and if you have some spray some elec cleaner on the connector / maf cleaner will work also

Have you tried removing the battery cable for a minute to see if a reset does anything
