    Replacing A TPS With Damaged Screws, How To

    A couple of years ago I got the idea of replacing my throttle position sensor since it was the stock part. I gave up after rounding the philips screws. I then tired to use a dremel to cut a slot into the screw heads but that didn’t work out too well. Recently, my absolute throttle position...

    4.0 OHV Absolute Throttle Position

    I’ve read threads on this site about the tps and it seems that 19.6% is the normal position for the TPS at idle. Mine has recently started dropping to 19.2% at times and I’m getting erratic rpms lately, like a 30-50 rpm change every second. The truck runs really smooth and the rpms stay steady...

I haven't had any major issues with the vehicle at all and have put quite a few miles on (160,390) it from driving it to Florida and back...

    Bucking at acceleration and Vibrating at Idle

    I have a 1995 Ford Explorer OHV V6 XLT. At idle it vibrates a lot and at acceleration it seems to sputter. All air lines seem to be tight. I just put a new throttle position sensor in and all my spark plugs are moderately new. I did just order new wires which I will try soon, I don’t usually...

    P2135 - Looks like TPS is bad

    Last night Driving at 70 mph through hills on cruise control I got a thunk and dropped out of CC, also flashing wrench on the dash for a moment. Manual throttle did not feel right but I could keep going. I noticed when I let off the throttle engine braking was much stronger than usual. Later...

Changing the IAC did fix the issue of it not staying on when it was cold but now I find it pulls hard as I slow down to stop and once I am about to stop the rpm's drop and it...

    TPS removal to clean TB?

    I want to clean my throttle body this weekend since its really bad, I've finally figured out how to remove the throttle cable by prying it off(I never found the way to remove it on here), now I'm just wondering if the TPS needs to be off the throttle body too before I clean it. I read somewhere...

    RPM Drop

    I'm having an issue and I'm lost for ideas. I own a 2008 Explorer XLT 4.0l V6 with 70k on it. Had the transmission replaced under warranty with a rebuilt unit around 63k. Now when I start the car the RPMs jump up to 2k RPMs for about 30 seconds then back down to 600-800. Then as I come to a...

    How to: Ford Explorer - Ranger TPS Test Procedure

    The PCM relies on the throttle position sensor (TPS) to determine closed throttle for idle and all other throttle positions for acceleration or deceleration. A defective TPS can result in unpredictable engine behavior. Testing the TPS is easy and costs nothing. You'll need a voltmeter with a...

    TPS mod + OHV question...

    Will the TPS (throttle position sensor) mod I've read about work on the 4.0 OHV and how effective is it? past experiences anyone? And also, what is the advantage of an OHV over a SOHC? is there any whatsoever? I have the OHV and the power difference of the SOHC is killing me :( :( :(
