## Description

This throttle position sensor is designed to match the fit and function of the original sensor on specified vehicles, and is engineered for durability and reliable performance.

Review: Straightforward Install - After having experienced the dreaded "decreased engine power" business, I connected my reader and found it said the error was with the Throttle Actuator Control (TAC); the little brain box mounted to the firewall by driver's side hood spring. So I purchased that from Rock Auto since desertcart wouldn't ship that part to CA for unknown reasons (even though it's been in use on my vehicle for the past 13 years straight, in CA). That install was simple, but then saw additional videos where folks said they did the same thing and the problem returned, and that the actual problem was the TPS. So I grabbed this TPS retrofit kit and installed in place (didn't remove the throttle body like many videos show people doing; to clean I guess). Removed air intake; two 5/16" nut driver hose clamps. Took photos of the existing 20 gauge wire harness wire configurations, as the new harness has all white wires (16 gauge). Used the shrinky-dink solder sleeves (Airnix SST-S21; from desertcart) to reconnect, using doubled-up aluminium foil as a backing for the heat gun (Wagner HT-400; also from desertcart). Don't care for mechanical crimping on applications like this, even though it comes with butt connectors. Soldered first connection, let cool before moving the wire out of the way, then repeated 7 more times for remaining wires, matching their position to old plug harness. Then came drilling out the rivets on existing TPS, to remove from TBI. Used countersink bit (as I had one, and allowed drill a little more access than using 3/8" drill bit) and needle nose to hold backside while drilling x4. Covered TBI with foil to make sure no drill cuttings got in there. Pulled off old TPS, noting the alignment of everything inside, so I could make sure new TPS was in same position. Rubber gasket on old was stuck to throttle body, so pulled that off. Replaced and bolted on with provided 7 mm hardware. New connector plug was a bit tight, so put some wire lube on male connector side, and it went right on. Reinstalled air intake, turned on ignition to send power, but not start, figuring the electronics would need a refresh for a few seconds. Turned key off, then started right up no problem. Everything is running fine now, and it seems to shift more smoothly. Prior to new TPS, trans would hold on to 1st and 2nd gear up to around 2500 rpm, with a hard shift. Now it let's go at right about 2000 rpm, which makes for smoother acceleration/shifting. Don't know if TPS is directly related to shift points, but it's definitely smoother now. Took me about an hour to do, and was definitely cheaper than having a shop do it, even with earlier TAC replacement. As I believe the shop will tell you that an entire new TBI is needed (of course).
Review: Great product. Get this instead of replacing entire throttle body. - I have this on my 2003 2500hd. Much cheaper than buying a new throttle body (which I did about 10 years back). It's been on there about 10 months now and has worked well. Fit well. Installation was pretty easy.
