Ok guys, everything I've read says you have to reflash the pcm after you've installed a new tps. Thing is, I had the pcm reflashed after I had the new throttle body replaced two years ago. If I install a new tos , do I still have to reflash it even though it has the newest flash installed?

 

What do you mean you re flashed the Pcm? is that a update for the Pcm or something

 

hey alsa. how much work is to replace the tps? and did it help.

 

Matt, yes it's an update for the computer. Lyric, it's not that hard, two star bolts and you're done. Apparantly the tps sensor is a common failure on our trucks. Im picking one up this afternoon. Takes about 10 min if that to swap out. 70 bucks for the sensor. I got a P2106 code this morning along with failsafe mode. I knew I was having a TPS issue for a few weeks now, but I think it totally fried this morning lol.

 

How do you update a pcm? Sorry I have no issues with my tps

 

Matt, it has to be done at the dealership. They hook up their computer and update the program on our computer. Sorta like a retune. I think it costs around 90 bucks. It can fix a variety of different issues from timing to shift points on the transmission.

 

Nice I have a 2004 f150 nbs xlt 4x4 with 163,000 miles and I get 11 mpg in the city should I try to update it?
