the wiring in my car is falling apart, i fear it was damaged by a flood at sometime before i owned it. so slowly ive been replacing the wiring and sensors.

i have had an idle problem almost a year now, and one of the last things for me to replace is the tps. got a new one as it wasnt that expensive. i look and there's two screws that hold it on. the heads from these screws on mine, are gone. broken off. wtf.

my first instinct was to just break the plastic around them, then try vice grips to remove the screw, hoping to save the treads inside for the new screws that came with the new tps. i have court in 15 hours, so I didn't do that. lol

suggestions?

 

They aren't screwed on, they're rivetted on. Remove them with a tap, screw on the new one, and you're done.

 

I thought it was a rivet head bolt so could cut a groove in the head and use a flat tip screwdriver to back them out?

 

This. Tamper resistant screw. Cut a slot in it and remove with a flat head.

 

You can do that as well.

I'm 99% sure they're yield snap bolts...but I'm 100% sure that 99% of people have no clue what a yield snap bolt is.

 

I think honda used snap off head screws so it would be tamper resistant. Anyways slot a groove on the top using a hacksaw blade then use a flat head screwdriver to remove them. After putting on the new tps make sure to use a multimeter to get it properly set.

 

every suggestion involves removing the entire air intake. that reall sucks. i guess i could remove the hood instead but ive gone down that road before....
the apartment complex i live in is in a nice part of town and its a breach of lease to do something as simple as change a head lamp...
I got a lot of dirty looks today

something else i noticed while at the junkyard today... why in the **** on the eg855 is the electrial wires to the front end passenger side of the car inside the fender as opposed to inside the engine bay like on the driver side. i cut a lot of wiring out of an eg865 today that was not done this way. maybe the previous owner of my car did some stupid **** i dont know.

What the **** is an EG855? Chassis codes don't use that many digits.

 

its what i look for on vins of other 5th gen hondas or the parts arent the same.
my vin starts JHMEG855

 

J = Japan
HM = Honda Motor
EG8 = chassis designation
55 = irrelevant

If the wiring was in the fender, and not in the engine bay, then yes, the previous owner tried to do a wire tuck.

 

yeah there are some subtle differences between the eg855 and eg865 , like the rear window garnish on the front doors. they're not the same. im sure most of the important stuff is as was the wiring, map sensor and water outlet i got today

 

Being that google doesn't know what they are either, I reckon you are correct.

The search did provide some interesting information of torque to yield for Head Gaskets and such so not all was a loss.

 

 

It's a special kind of bolt that is rarely used, and is meant to be semi-permanent. The bottom looks like a normal bolt, with regular threads. There's a flange at the top of the threads that looks like a thick washer. Above that flange, there's an unthreaded solid bar of varying thickness, depending on the torque snap value of the bolt. At the top, your standard bolt head. Basically, you go at it with the most powerful tool you have, and when the bolt is at it's specified torque value, the bar and head snap off above the flange. Give it a quick polish, and you have an unremovable stud.

They're VERY rare, and why Honda decided to use something similar for the TPS is completely and totally beyond comprehension.

 

shear bolts.

 

Yes. This is the name for them. But NotARacist was on the right path also.

They're bolts with heads that are designed to snap (shear) off at a certain torque value. Honda zaps them down till the head breaks off...which makes the fastener tamper resistant.

You can cut a slot into them and turn them with a flat head screw driver. Remove the 4 bolts (OOMGSOOMANYBOLTZZZZ) holding on the throttle body. Then it will be easy to cut the slots and remove the TPS.

It's recommended that you get a new TB gasket...but you can reuse yours if you don't tear it. You will also need to set the TPS WOT and closed throttle values.

 

Aha, yes, that's the proper name for them! Thank you.
