No, holding foot on gas will not keep it running.
Go to the throttle module connector which is the one on the bottom and make sure we have battery power with the ignition ON for both the green/yellow wires and ground on both black wires. Then lets go to the sensor.
On pin 10 white wire you should see 4.1V @ IDLE (DECREASING VOLTAGE WITH ACCELERATION)
On pin 2 white wire you should see 0.8V @ IDLE (INCREASING VOLTAGE WITH ACCELERATION)
On pin 1 white/red you should see 1.4V @ IDLE (INCREASING VOLTAGE WITH ACCELERATION)
Richard I followed your directions listed and all tested good. I tried placing a screw driver in the throttle to hold it open and the vehicle continues to run until the screw driver is removed. Is that signs of a defected TPS.
Ok, I will replace the throttle body assembly which is rather pricey, but I guess that's the cost of owning a jag.
RICHARD, I HAVE REPLACED THE GAS PEDAL, THROTTLE BODY, CLEANED MAF AND ALL ELECTRICAL CONNECTION WITH CRS CLEANERS, AND STILL NO PEDAL RESPONSE.
I performed the electrical test at the TPS and got .009v at all pins.
The is running but code 1573 and the fail safe engine code will not clear.
It looks as if the wire from the TPS connector is connecting to the alt. If so could that be the connection problem.
That gives me 4.89v
yes it moves
I replaced the TPS but got no change
I changed the TPS again and it working now.
Thanks for your help.
