02 4.7 Throttle position sensor

Just thought I would take a minute and tell you the issues I was having.
My Idle was kinda eratic. when i first cranked up it would Idle upwards to 2000 rpm and fluctuate. Eventually it would calm down. Coming to stop it would drop below 500 rpm on occasion.

Installed new TPS.

Idle is now corrected. RPMs sit steady around 650.

The Transmission is now shifting much smoother expecially on the downshifts. Transmission no longer Jumps from 4th and 5th on country roads. Gas milage has improved. Feels like I got a touch more power also.

Really amazing what all that sensor helps control.

Install was a breeze. I did not have to remove the air box thing. T20 torx bit and extension.

Re: 02 4.7 Throttle position sensor

I went through a similar experience on my '04 with the HO when I got it. Did you go with an aftermarket or Mopar piece? I went with the Mopar piece after reading tons of stuff on teh interwebz.

These things seem to be notorious for acting up. Especially the aftermarket ones.

Re: 02 4.7 Throttle position sensor

Hi Folks,
Mine just arrived this morning - MOPAR part number 05017479AA for my 2001 4.7.
Is it necessary to disconnect the battery for the TPS or is it just for the IAC valve?
Cheers
Paul.

It's a good idea so that the pcm can immediately start learning the new tps, but you don't have to disconnect the battery.

Re: 02 4.7 Throttle position sensor

Hi,
Changed it last night - easy 10 minute job.
It immediately made a difference to the revs at start up but I can't comment on how it drives as the wife has it today
Will comment later with driveability.
Regards
Paul.

Re: 02 4.7 Throttle position sensor

Hey guys. I heard you guys were having some of the same issues i was having. My TPS is starting to go out and i was woundering how much the OEM Mopar TPS sensor was. It is throwing the check engine code for it. It is a 99 WJ 4.7l.

I just replaced mine with a BWD piece from Pep Boys that was about $30. So I'd think that the Mopar piece should be about the same or a little more.
