Truck was shifting hard when I took it for a test run. Before I swapped the injector pump it would shift hard and early at 1/2 throttle or less but shift smoothly when throttle was above 1/2 way. OD off light just started flashing today so I cruised it back home and pulled the codes, got 67, 43 and 63. Unhooked the batteries for about 45 minutes,hooked them back up and took it for a quick ride again...same thing, light started flashing, pulled the codes and same codes
I previously thought the problem that I was having was the metering valve sticking, when it's warm and in drive or reverse it will start running rough and shooting black smoke out of the exhaust, same when coming to a stop. If I hold the breaks and bring the idle up some it will smoothen out and stop smoking, also it doesn't do it when in neutral and coming to a stop, only when trying to stop in gear.
Code 43 TPS below idle spec...
Set it to 1.07 at idle and 4.15 at WOT
Code 63 Throttle Position (TP) circuit fault below minimum voltage
Am I right in assuming that these 2 codes are both related to the TPS being out of range? It was at a 1.24 when I checked it, I then set it to 1.07 at idle and 4.15 at WOT.
Code 67 Neutral Pressure Switch (NPS) circuit failure, circuit open.
From my research here, I believe that something is wrong with the Transmission Range Sensor. Is this the plastic electrical piece that is on the passenger side of the transmission? I unplugged and looked at it and it has transmission fluid in it...Am I right in assuming that it is wasted simply because trans fluid found its way up in there? And the question that I am most concerned about, can the rough running and black smoke when warm and idling in gear or reverse be related to the sensor being wasted?
Thanks.
