I'm getting a bunch of error codes and have been able to track down most of them but this one still eludes me, P-1596, have'nt been able to find it anywhere. other codes werep-0216( and Rig is going in for warrannty on this on wed.) P-0500,P-0122. anyway any info would be greatly appreciated.

 

P1596 Speed Control Switch Always High

Got me on what that is exactly though.

thanx mulder, these codes have me chasing my tail .

 

Did a little more research,
and the 1596 kinda conflicts with the P0122 Accelerator Pedal Position Sensor Signal Voltage Too Low.

well its going to the doctor on wed maybe they can figure this tempormental s.o.b out

 

P0500 (M) No Vehicle Speed Sensor Signal No vehicle speed sensor signal detected during road load conditions.
P0500 (M) No Vehicle Speed Sensor Signal A vehicle speed signal was not detected

P0122 (M) Throttle Position Sensor Voltage Low Throttle position sensor input below the acceptable
voltage range.
P0122 (M) Accelerator Position Sensor (APPS) Signal Voltage Too Low APPS voltage input below the minimum acceptable voltage.

P0216 (M) Fuel Injection Pump Timing Failure High fuel supply restriction, low fuel pressure or possible wrong or incorrectly installed pump keyway

P1596 Speed Control Switch Always High Speed control switch input above maximum acceptable voltage.

 

i found the plug attachment on the rear diff. was unpluged a couple of weeks past could these code errors come from that.(plastic clip that ataches to the top of the rear diff)

 

That would account for the P0500, as that is the vehicle speed sensor on the rear diff.

would i still get some needle play if that was unhooked cause i think my speed needle was still, working whether or not it was working corectly i'm not sure?
