Accelerator Position Sensor - Difference between 1995 & 1996?

22545 Views 14 Replies 8 Participants Last post by  MJPliska
Also known as Throttle Position sensor. When looking up part numbers for pedal assemblies, there is a different part listed for 1994-1995 trucks (F5TZ9F836A) than for 1996-1997 trucks (F6TZ9F836AA). The 1996-1997 part is MUCH cheaper, and also has the sensor available by itself from Dorman. Does anyone know what the difference is between these sensors or pedal assemblies? Can I put a pedal assembly from a 1996-1997 on my 1995?

Thanks,

Thanks Rodney! Do you know if your 1996 sensor uses gold contacts? I just bought the Dorman sensor-only part for the 1996. It has zinc-plated contacts instead of gold like my factory sensor. It also appears to be 5.0 k-ohm versus 4.5 k-ohm on the factory unit. The resulting voltages are also a bit off from the factory unit: factory idled at 0.65V, IVS switched at 0.88-0.90V, and wide open it was 3.90 V. The Dorman unit is 1.12V idle, 1.28-1.30V IVS, and 4.38V wide open. Just driving it in my driveway it seems to work ok.

Thanks,
Michael

The contacts on both the 96 and the 00 TPS are gold colored and they both have a part nunber of F5TF 9F832. Is that the same number that's on your 95?

Yes, that is the same number as on my factory sensor. The Dorman part is #699-200. It is externally the same appearance except for the zinc (instead of gold) plating on the electrical contacts. As I noted above, it seems to be slightly different electrically, but this may just be manufacturing tolerances. So far (90 miles) it seems to work fine. It's about to get more of a test, as I am leaving in a few hours for a 450 mile drive to Boise, drag racing while there, then the trip home. I just hope this solves my remaining off-idle stumbling problem!

Thanks,
Michael
Update:
So far so good with the Dorman sensor. It is noticeably more sensitive (i.e., less pedal movement for the same engine response), which would be expected with the higher voltages. Unfortunately I only had 3 passes in Boise (despite getting there right as the gates opened) /ubbthreads/images/graemlins/frown.gif . The truck was launching a bit slow, but I suspect it was mostly due to the heat (corrected altitude over 6000 feet). The previous stumble was not present, although it sometimes went 5 or 6 passes before without seeing the stumble.

I bought the Dorman sensor from the local Carquest store. They had it in their central warehouse in town, had it at the local store within 2 hours. Price was $61.
