Do I just disconnect the negative battery terminal?

Will do the On board code check. If then a reset is necessary how do you do that?

Thanks!

chekc all the connections, did u replace the paper gasket ?

Mr sauga

holymoly

paper gasket?

Code 05 05 A OK.

andrei3333

when u take off the TB there is a paper gasket between it and the intake manifold

here is a shot of my dirty TB with the paper gasket stuck to it

here is the paper gasket on the top and the metal gasket for the IACV on the bottom

dont cheap out, its only a few dollars for the piece of mind

hey BTW r u on TMEC?

I reused my old gaskets for TB and IACV and it was OK. What did you use to clean TB ?

that is the dirtiest TB I have ever seen. WTF happened?

Sometimes lights come on when you clean stuff. It happened to an Altima that I drove at a car dealership. I almost bought it, but then they cleaned the engine(including the TB) and it ran like crud afterwards and the light came on. It drove really nice up until then too. Try disconnecting your battery and reconnect it and see if the light comes back on. Is your car still running normal?

i bet it has an erratic idle too...this happened to MANY 5.5 gen guys who cleaned their tbs..ses light went on

andrei3333

no guys he got the code 05 05 that means all systems are functioning to proper parameters.

Thats not the dirtiest TB ever the car has about 219.xxx KM, wanna see some more pics of that job ??? 56K killer

Perhaps when running OBD is cleared the code, but "Service engine soon" is gone. I didn't unscrew the TB, just reached in and sprayed Canadian Tire's "Throttle Body cleaner" and then wiped.

Haines manual strongly urges not to clean at TB at least with chemicals.
Interesting.

Wow, Andrei, that was some grungy looking TB. Sure it runs smoother now.

I've had the CEL illuminated after TB service before. Never a code either. I think the O2 sensor gets crudded up until you can burn it off. My CEL would go off after a couple of days normal driving. Good god man that is one nasty **** TB.

here is some more for whoever want to look:

I cleaned my throttle body and did not have any cel to contend with. The Haynes manual says that if you make certain test through the harness that you will have to though.

Why don't you use the screw on the side of the ECU to reset the SES light? It's immediate.

I did the TB removal thing on my I30 (156K miles) it looked that bad. I didn't do the IAC though & probably should have.

I got the CEL on now though. It indicates 0100 (MAF) is at fault. Still runs fine. I'll let it go for awhile & maybe clean the IAC, then I guess I did screw up the MAF when I accidentally dropped it in the process.

andrei3333

yeah thats the one i took out of my car this summer, i dont know the complete history of the car but it is possible that this is the original one and if it is its got like 215000 KM on it ( thats like 135000 Miles or something)

so yeah these things do really crack

The reasons behind it are different. Stick to the 5th gen forum, where you have a little more knowledge.

wayne937

Most likely if you dropped the MAF sensor you broke the small hot wire sensing filament that measures the air flow by changes in voltages as the air cools the filament. This wire gets hot and over the years I am sure that it will crystalize. It's like dropping a flashlight...the wire in the bulb crystalizes from the heat and will break easily. I am sure you will have to place it sooner or later. By the way, I think the CEL or (MIL) as it is also known, is different then the SES light. To me the SES light lets you know when your engine is due for a service and the MIL is when a code has been set in the computer. To clear that code you will need an OBD11 scanner. Auto zone and advanced Auto Parts will most likely reset it for you. At least that is how my wife's Toyota is set up. At every 5000 miles the SES light comes on and then we know it is time for service.

Yay for the cool **** Bravo!

andrei3333

SES = MIL = CEL no?

sorry wayne, u dont need obd2 to clear the code on a 4th gen

oh and that toyota comment is funny

papo020

That's close to ONE of the dirtiest that I've ever seen! But I think the one of the 94 Honda Passport that I bought had the worst! That had crud built up on it and believe it or not I had to get a ball pein (i think thats how u spell it) and a small chissel to get it all off and then scrape the rest of it off with a puddy knife! lol needless to say; that's why I sold it!

SES = Service Engine Soon light (97-07) MIL = Malfunction Indicator Light (FSM standard terminology), CEL = Check Engine Light (95-96)

So yes, you're right.

andrei3333

right, same function tho
