Throttle body GM 55561495 OEM vs NEW disassembled view

Compared the OEM throttle body to the new one I just bought today. Not to much changed by eye, but the new one looks to be better made than the OEM in terms of machine work at least, no sharp edges ect. The large black plastic module on the side has a slightly different design. I did note the OEM one has a needle bearing in one end which is bone dry....I did not open up the new one to see if anything changed under the hood or not. There are a couple of connections inside the OEM one that are far from solid and I could sure see a poor connection on either one of those. I would conclude by review that cleaning the throttle body does nothing other than perhaps making the butterfly valve operate smoothly...no IAC in there that cleaning fluid would hit. Pics to follow

To gain access to this needle bearing, one could in theory drill a tiny hole in the "frost plug" that seals it from view....add some oil, then reseal the hole that was drilled with a weapon of the do-ers choice. Oil will reach the bearing if applied to the shaft inside the throttle body housing, if the angle is correct, but certain oils may cause the seal to swell as may any cleaners used to clean the TB. This bearing was lubed but the lube had become "gummy" in mine. I am more apt to think there is issues under the black plastic "hood" causing these TB's to fail....but well lubed bearing and shaft could help those with the unstable idle issue.

Interesting pictures. I'll have to see if I can get some shots of my 07 throttle body. It came off the 07 engine I have in my 05 which is cable driven.

So, those pictures are of the failed TB? Did you find anything that might be the cause of the failure?

On the black plastic cover there are to female electrical plugs...on the TB there are two male electrical plugs...that connection is very loose but I can not say for certain that is the cause of the failure. If that connection degraded, which I think it did, it would cause intermittent loss of power to the TB and result in the throttle closing....a stall. Also varied electrical flow through the poor connection could cause idle surges, erratic idle.

The needle bearing on the TB is also "gummy" whatever was used to lube it doesn't stand up to the heat. This again could cause some issues.

The plastic gears which transmit movement from the electric motor which controls the butterfly, very cheap I could see them binding very easily.

I may one day, clean and lube this one all up and reinstall it to see if it works as it should. If it fails to do so that would certainly indicate the little electric motor in there is the problem.

So, it could have been multiple things. No real smoking gun eh?

Well the smoking gun in my opinion is the overall poor quality I am afraid. My car would stall without notice, it doesn't do that anymore, but your right nothing jumps out as "broken"........If I had of taken the new one apart to see what has been changed in it......that would very likely pinpoint the problem. The black plastic cover is redesigned on the new one, it houses the female electrical connection.....that's were I put my money.

I found my 07 throttle body in the garage and brought it in the other night. As far as I know it was working when I pulled it off the engine. I'll take it apart and add to the images in this thread and hopefully someone else with a failed throttle body can figure out what is going on.

Hi I have to change TB from my ECOtec 1.6L Pontiav G3 2009, but the AC Delco is a better piece to change it?, mi fuel average are very worst....

Or exist a better option?...

pleas search te part # here...

RockAuto Parts Catalog

ACDELCO Repuesto # 55561495

nobody?, bump!!

The AC delco would be your only option. I'd call a dealership, sometimes, they sell parts cheaper than aftermarket companies do. There is a fat chance AC Delco is the manufacturer of the genuine part too.

Today i´m going with an GM service center, and tell me, mabe requires calibrate the Throttle bod, y hope this worst, because they tell me the ralenti was inestable and they can correct it, i hope so...

Because that repair cost abut 46. usd....

Versus the 630.00 usd cost from TB at the GM dealer, its a thief...

I´m gonna doit the thursday..

Traductor




On Thursday I took the car to the throttle body calibration without thier told me they repaired the connector, it loses voltage, and this raises the throttle body does not respond as it should ....

My consumption improved significantly as well, the car feels much better, throttle response, I was finally satisfied with the service, the car to accelerate, seemed to suffocate, ie the car and was vacuuming and the kite would not open this situation was solved with this service the cost was 26.00 usd ....

Anyway, talk to your service, I found online for as ideally change the connector ...

The told me that it opened and again tighten the harness connectors that vivraciones lose heat and generate tension and signal errors and false contacts, I'll ask anyway idle calibration for these effects and it is 100% ...

For now the car idle only fails when I fill the fuel tank when parked upside down and bent ...

I think this was verified that my throttle body did not fail, and I was told that the throttle body needs calibration fails and dirt from ensusciarpor and this generates errors kite position ...

I commented, first the car started to fail, but the problem is still not in the throttle body, insist that it is in the connector ....

The technician told me that the throttle body endurance and showed this was due to vibration, the connector loses tension, but I adjusted.

However after this repair significantly improved vehicle reviews, comparing with the previous review of pollution control, the hydrocarbons decreased from 50 to 0.7 and the oxygen that was nonexistent appeared in measurements, the smell of gasoline almost disappeared ...

As I mentioned with the same dealer I talked to him about these two issues the P2135 connectors, both set out what needs to be changed is the connector. He insisted there.

But what happened, after adjustment of the connector, as enunciated greatly improved the engine revolutions stabilized mostly, but the fit was only light connector and introduced faults.

On January 14 return to dealear and they did a software update and it seems all right, on Friday again, failure to file, I still insist that the connector should be changed.

It is a fact that the distributor in Mexico do not have it in stock and may therefore be reluctant to change.

Well I think speak for another review ...

although I've found a lot of error P2135 and all the connector indicates change, tell me that the engines are iguals, however I do not understand why they are different, the error is given by the same...

Well I think speak for another review ...

In case of changing the throttle body, maybe I would put this in 70mm, which is coming boreado, as seen only changes the throttle body, and kite position sensors and motor are retained OEM ...

Change the oil filter piece, and the water pump, te cooling sistem was vei bad in this vehícles, almost change all, it causes the motor harness, break it and seend, bad singnals to the ECU...

Whel I apreciate your help, I sell the car, and buy an Suzuki Swift '13, best regards...

it did disappear for 4 or 5 months but same problems are back again now.

Yes this the worse car I ever owned, I totaled up last years repair bills on it and it's just over $5800 and that's 95% parts no labor. I drove 18,000 KM with it, repairs $ 5800.00. Is now due for timing belt ect......33 cents a KM repairs and maintance, my Freightliner which sees 300,000 KM a year is 12 cents a KM....and they both use about the same amount of fuel.

I think as car was not so bad, but I I have two problems, the first is that the engine was allowed to ride in Mexico, came only two years, and despite share parts with Astra and Cruze 1.8L, the pieces are not in existence.

The agency is a robbery one piece filter base cost me at $ 653 USD and the water pump in 250 usd. more labor.

Of the 250 usd sent me both original to my door from the U.S. but it took a month to arrive, in the inter burst hose heating, the agency ordered, stayed a week without a car and left at 47USD, that I changed it.

Then I panicked just mae tired of being spent on the cart to make it work as it should, even paerformance, the last 5,000 km was a total headache, with high fuel consumption, as if he brought a 2.0L.

In this sense or nearby parts and cheaply, you need a spare each was imported, with the problem of time and also the cost.

When the machine arrived not guess when the imported too.

In the agency I scanned the engine and determined that it was not the TB that was the harness, so I changed it too. I went in 330.usd already installed.

The origin of all:

GM has serious problems with their cooling systems, the degree of fracurarse the coolant reservoir, hoses to 20.000 miles flew the first hose, so did the 40,000 and 60,000 miles, the engine warming and degrade the electronics and other components such as the oil base.

From there all I had to change ...

This will state that the engine to be very commercial model for only two years left here, I had no parts availability (for other faces, for a mid-range vehicle floor) was to pay the parts that brought a audi.

In order to thank the Forum the opportunity and support, long and sometimes little to solve my problems, I hope to serve him somebody more references for future repairs.

I can say I am happy with my Suzuki Swift 2013, I took account of the g3 and the good treatment he gave was sold flown, lacked the timing belt change other 650USD which I refused to pay, for consumption fuel, finishes, which are higher than the G3, if sacrificed space, but not always carry the trunk full, anything that can continue to support the oppor gladly 1.6L ECOtec mail, greetings and thanks.
