I had some problems with my boat this past weekend. my mechanic read the codes and it pointed to a PPS (pedal position sensor). I assume that this part is from a car and can be purchased at a local auto parts dealer. Does anyone know what the P/N# for this item would be?

We had the same code come up on our boat, same year, same engine. It happened when throttle was near idle, not fun when trying to dock. Had the part replaced at the dealer. Don't know if it is a standard part. It was not cheap.

forget the code number but it pointed the finger at the the PPS.
The part is $235.00 from my local dealer, I will just buy it there.

Do you have a part number and where it's located???? I may be having he same issue. Once I scan the code I will know for sure.

I went to my local dealer to buy the $235.00 part and it was the wrong one, and you have to buy ( $575.00 Teledyne mfg.) the whole throttle assy for that year and model of boat. The manufacturer of the sensor only is BEI. The number on the unit is 9861 0406. I am going to try to source the part direct from them.

I did disassemble the sensor and cleaned off the contact portion of the potentiometer. It was assembled at the factory with a clear grease. I wiped this used grease off and it was very black. I reassembled the unit and going to give it a try because I wont have any option for this coming weekend. I will let you know how it goes, and hopefully post a picture.

The part is located behind the drivers side throttle panel.

I took the position sensor off the throttle assembly, opened it up, cleaned it, put it back together, and it worked without alarming a code. Fingers crossed.

That doesn't seem like a MEFI 4 DTC code.

I assume you have the throttle by wire system, if so are we talking about the that part?

I had the same issue three years ago on my 05. They wanted close to $600 for the whole thing. I called Chuck at BAWS and he told me that they either are fail or if it is intermittent (which mine was) they can usually be taken apart and cleaned and tightened. I did this and have had no problems for over three years and close to 400 hours now. I them saw someone post this link so I book marked it as I think (not positive) that it is the piece that goes bad and thought I may need one someday.

So we are talking about the TPS. I was unsure because I couldn't figure out why one would cost $600 bucks!!

Can't repeat,

The $600 is for the whole throttle control assembly and they will not sell the sensor seperatly.

Ah, so it's like the fuel pump canister, you can't get just the pump from MC.

Thanks for clearing that up for me.

Yes it looks very similar, same brand name as well.

Posted this a while back, my mate in OZ found this supplier as an alternative to replacing the whole unit through Mastercraft. Is a perfect replacement. Same as link I assume. Have fun.....

I just purchased the TPS from Mouser. Thank you! I think this is a going to be a great workaround instead of buying the whole dang throttle lever and now wiring harness that you have to have. With labor close to $900 from my local shop (boat town, Austin TX). However how the heck do I install this? Do you have to take off the entire right body molding that's all black, and houses the speaker? Any insight on how to get to, and install is appreciated. thanks!

I believe you can just remove the aluminum panel that the throttle is mounted to. On mine I can just remove the top screws on the black panel and gently bend it back to gain access to the backside of the throttle linkage.

Did you problem get solved? Im having the same issue, the dealer mechanic has replaced the throttle body and another sensor and it's still not working.

Mine failed last summer, but after cleaning and reassembly of the sensor , I haven't had any issues with it.

Craig - when your sensor failed, what were the effects? When you push throttle down, no acceleration? Was boat put into "limp mode"? I am having a similar issue and just trying to diagnose the issue.
Thanks for any input.

2006 Mastercraft Prostar 197 with MCX 350 Vortec engine, factory Perfect Pass, and Drive by Wire throttle. Over the past year, I've experienced intermittent episodes where the idle becomes a little erratic. It is usually fine for some portion of the day, but it starts to act up. Idle typically surges erratically but does not drop below the typical 650 rpm. Occasionally, the check engine alarm goes off, and we turn the engine off. All this behavior occurs when the perfect pass is off. Is this behavior consistent with the problems seen by others in this thread? Were others able to replace the BEI sensor and resolve the issue? No recalibration necessary?

Any luck with this issue? My 05 X45 is doing the same thing.

I have a 2007 X-Star and my Mechanic said he called Texas MC and they told him I would need a Throttle Body Assembly they said that is the part that usually goes out and not the sensor. But the part for the Throttle Body Assy is $900 - the Sensor is $350.

My problem started early in the summer the Chk Engine Alarm would go off (it had been going off and no codes would come up) Well I finally cracked a head and had to rebuild the engine. Anyway before and after the rebuild the Boat would go into safety mode meaning it would give enough power to plain out. I would then just kick it back to idle turn the boat off then back on and then it would work. Near the end of the summer it seemed to happen more often like 2 or 3 times each day. In the beginning of last summer it would just occasionally happen.

I guess my question is should I have him remove and disassemble the Throttle Body and clean? Or does anyone now where I can find this part for less than $900???

I am bumping this thread for future reference that this sensor is the correct part for the DBW system. I was having an issue where my boat was revving to ~2,000 rpms every time the boat is pulled out of gear. Replacing this sensor fixed the problem and was a direct replacement that took me 20 minutes from start to finish.

Glad you got the boat fix. Strange that you didn't get a check engine light on that. Well, I'm not even sure there is a code for that sensor. I'll have to look.

And that sensor doesn't go on the TBI but on the throttle lever at the helm? I thought this thread started out about TPS?

Regardless, nice find and fix.

It started about the Throttle Position Sensor or Pedal Position Sensor, as some call it. It is a little sensor on the throttle linkage. After replacing the sensor with the new part, I took apart the old one to see if I could see anything. Long story short, the dielectric grease had turned an ugly black, not the usual translucent white. Other than that, I saw nothing visually wrong with it.

Regardless, nice find and fix.

Very excited it solved the problem. Only $65 and the cost of gas to get out there and back. Much better than dragging the boat home and having it sit at the dealer for weeks on end.

Yeah for some reason I overlooked the PPS in the OPs post. Somewhere I read TPS and just followed that.

Same issue for me this year. 2006 x2 mcx. Boat would random rev at idle. Makes for interesting dock. Lol. Pulled switch at helm, opened, cleaned with contact cleaner, reinstall. Thanks Sodar for posting the pic of the backside. Be carful opening the switch. Spring came loose on me and was fun figuring out. I got scared and ordered another from Mouser like others but actually installed the old one once I figured it out. Passed garden hose test. Lots of great people here. You all saved us $1000. Dealer quote. Thank you!

How did you remove the actual sensor? The one pin going into from the throttle arm seems to have a fancy small clip holding it in place on the inside of the sensor. I have the old sensor taken off the throttle with the little gold arm still attached to it. The sensor is disassembled in half....I was wondering if there is a way to prevent having to open up the new sensor I ordered when it arrives.
The spring came out of the old one on me...not sure how it goes back together now or if it even matters how the spring is positioned.

The metal lever just pulls out from the sensor. Nothing holds it in the except the two screws when it is mounted to the throttle assembly.

We have a 2007 xstar and the throttle was intermittently working and the check engine alarm would go off every time we started the boat. I took it to the dealer and they said it was probably the throttle position sensor but we would have to replace the whole throttle ($600 for just the throttle!). My husband found a thread here that someone posted that they took apart the facade, took the sensor out and cleaned it, and it had ran fine for them for 3 years. My husband did the same thing and our boat has now run great since without any alarms going off!! I would try cleaning the sensor before replacing it! If you need the part number (which I don't know if it will be the same for you due to the difference in year), there is a thread somewhere here that has it posted. It was under $60!
