Project Double Gnar - Misc Engine Sensor Gone AWOL

At some point I'll group all my ridiculous posts together and make it into a memoir or something, but in the meantime.....I was trying to clear up what I thought was a TPS issue by cleaning the throttle body and managed to wiggle some wires out of place in the process.

Now I assume this was supposed to be a plug and this ridiculous wiring job isn't factory but as I don't know what it is I don't know how to look it up. It on the right side of the motor just below the top and all the wires seem to come out of another loom but it's all crisscrossed so I can't tell where anything starts. The four wires that go into a 'socket' of whatever have individual male end leads of sorts and given how I looks I have to assume this was someone's ill-fated attempt to make it work without replacing a bad plug or trying to bypass something.

Also finally got some miles on it and it threw a CEL, though this time not for the throttle (which I was expecting) but it's giving me a bunch of misfire codes so I'm assuming that's perhaps what these wires are for and that I must have put them back in the wrong spots (they weren't labeled I was just going with how they were bent and hoped for some luck).

Any help is appreciated as I'm hoping to stave off another expensive trip to a shop after having to deal with a whole new driveshaft, full trans rebuild, and a full power steering rack/lines/etc. replacement all in the last month.

 

Might help with that cover removed, assuming it's the 4.7L cover ?
Also it would show the number of wires better and the color code of said wires.

Once determined what it might be for, the 2000 Electrical Wiring Diagram showing circuity and connector might be helpful !

 

Thanks, and wow it looks like it's the throttle position sensor that is supposed to be there instead of four separate wires. Any reason someone would do this on purpose and any idea how to tell which was supposed to go where?

Would this cause a cylinder 5 & 7 misfire

Lastly how would I go about correcting it, aside of ordering a new plug/sensor?

 

Given the location and colors I can see Pink-Blue(P-L) and Black-Yel, I believe it's your TPS !

 

100% agree based on the wiring diagram as well.....but how do it fix it? (Assuming it's not supposed to be that way)

 

Temporary ?....perhaps someone with a 00-03 can grab a pic of theirs. My 04 is motor and sensor so it has 6 wires !
I'm looking at finding the connector in the EWD which might help !

Long term....check out Salvage yards if any close by and grab what you feel you need !
Longer term....hell if I know !

Removing that cover and showing connector will help tremendously !

Edit:....90980−11037 should be part # if you have to order !



Edit x 2.....T2 connector(TPS grey connector) obtained from 2000 EWD !

 

It appears his gnar-gnar connection is correct according to your picture @Sirfive, I would suggest he pulls them pins and re-connect without tape for a test and make sure they are seated good. There should be enough clearance between pins to at least test.

 

Pouring out here so pulling the cover will have to wait and it looks like they added an extension to the wires? Or pulled back those rubber/plastic stoppers for some reason? At the end of each is the sort of metal contact I've seen connect like speaker wires maybe. If we get any breaks in the rain over the next couple days I'll give that a go and take more pics

 

Seems the socket that the part number references isn't the issue do you know if the wiring harness that plugs into it can be ordered?

 

Also in the meantime does anyone happen to know if the TPS sensor wires being borked would cause the misfire codes (P0300, P0305, P0307) that I got?

 

They probably broke the connector housing and left the pins loose. Then just shoved them in with some electrical tape wrapped around them.

You can probably find a matching connector from many cars at the junkyard and put them in the correct location to fix.

 

Given that the TPS helps with correct air/fuel, it can indeed contribute to misfires....numerous misfires P0300 !
What could eventually happen if you do not check those plugins, you'll put her in limp mode !

 

Makes sense and I was able to drive it about 40 mins (all side roads) round trip, shut it off and back on without an issue aside of it not being happy at idle, sorta chugging a little if I had to sit at a light. Surprised it didn't throw me into limpode after seeing the codes when I got back from picking up a few things.

 

Ok so first pics with the cover removed:

 

I pulled off all the electrical tape and slid the rubber things up to where they should be based on the pic from SirFive. Plugged them back in, and felt like I got better contacts now that I wasn't fighting with all that tape in the way. Does look like someone broke at least one or two of them somehow and soldered them back together, so I couldn't get the rubber bit all the way back to the top. Cleared the codes, and drove it around the neighborhood, didn't have an issue and codes didn't come back but it was all of half a mile.

 

Good to hear and if having to drive it much, you plan to secure it a little better so the ztttt doesn't get out !

Do you have a junk yard, pik-a-part in your area ?
My plans are to go by our Raceway pick-a-part lot wed or thur. I would be glad to see if I can find the male end off a 2001 they have, in fact the 05/06 they have might have a 4 pin. Regular mail should only be a few bucks.

 

Only one in the area but highly doubt they have any tundras on site, it's pretty exclusively all cars broken down from the highway that nobody wanted. Would an 05/06 male end work with what I've got? Like I said it goes down into multiple looms so I don't even know where to connect it to or where it comes from.

 

Minor update, took it to get gas. Quick 15 miles roundtrip to the cheaper station made for a decent little test. No issues, and no lights. Was pretty straight shot there all between 35-50ish. No CEL by the time I got back so I'm putting it in the win column. Didn't get stuck at more than one light but didn't notice it hesitating as much as it did on Sunday.

Guess I'll keep looking for a set of wheels/tires so I can try to put some highway miles on it to see about finally passing the emissions test I failed like 4 months & a few repairs ago.....

 

Slim chance but I'll be looking at the 06 for other reasons.

It proceeds down into the main wire harness(no mans land). If/when you find a male plug, preferrably with at least 5 in. of wire atttached, you'll properly splice those wires into the wires you have plugged in to the female plug.

 

Appreciate that just don't think there's any finding the source without doing a full tear down.
