Po725 stays in limp mode

You should NOT be driving this vehicle if it is in limp mode. You will need to pay a Good Auto-electrician to look at this problem.
All modern cars and trucks are fitted with electronic control units referred to as the PCM and the TCM. P1698 refers to these units not communicating properly with each other. So the vehicle goes into a safety set up until the problem it fixed, Limp Mode.

code p 0705 refers to transmission range (TR) sensor /switch--PRNDL input--circuit malfunction====causes --wiring---TR sensor /switch
replace the TR unt

IN that event you might also have a check engine warning light or other significant warnings on the dash.

The computer sends the vehicle into limp mode to protect the engine and /or transmission from damage due to a fault or faults it has detected in the system.

You need to get the vehicle to a good workshop where they will scan it for faults and see what other irregularities there are with the driveline operation, in particular the engine.

UNTIL you address the problems and have them fixed the vehicle will stay in limp mode or, in the worst case, the computer may ultimately shut it down altogether and you won't be able to start it again. So have it looked at by a competent ISUZU truck as soon as you can.

use a fault scanner to reset the CPU program If everything is good it should work . if not the fault codes will reappear and you will know what to fix.

have the fault codes read to check for reason it is in limp mode. Fix any faults found and use the scanner to reset the ECM program as the dead battery may have corrupted the program

the .pcm puts it in limp mode and it will stay in mode until light is turned off. You need to get the trouble code, repair it, erase the codes (with a scanner that retrieves the codes), and then you will be out of limp home mode.

Mercedes suffer with the radiator whereby the gearbox oil and engine coolant leak in together and cause gearbox to stay in lower gears like limp mode this will also give incorrect readings on coolant so worth getting both gearbox and coolant checked i beleive they call this a glycol test??

The only time a vehicle goes into limp mode is when there is ****** problems, so I would take it to the ****** shop for code retrivel and if I am not wrong there might be problem with the Input/Output speed sensors BUT do have it checked first.

take it to jaguar and have the software checked and any fault codes removed ,

It was a temporary fault that put the car into limp mode (a safeguard operating condition designed to protect the transmission in case of serious failure). Sometimes a transient fault can occur, and the car goes into limp mode just to be sure it's not for real. Shutting off and restarting the car is the usual way to clear the fault and return the car to normal operation - if the problem was real, the car would've stayed in limp mode after restart, or gone into limp once you started driving again. I wouldn't sweat this one, since it went right back to normal operation.
