Default '96 ECM

Where is the ECM on the '96 I4 (auto trans) Camry, and how does one
remove it?

Car was Made in Japan, if it matters.

Any history of problems with this ECM?

Thanks,

Michael

====================
Michael,

Are you really sure you want to do this?
The car will be next to useless without the ECM.
Have never heard of one going bad.
They're behind or under the glove box. Could be behind the
plastic cover on the floor there. Just unplug the wiring connector to
remove.
The wiring bundle comes from the DLC under the hood.
www.camrystuff.com should have your manual
Tha part about the ECM is in the engine troubleshooting section.

Thanks Daniel.

I just wanted to access it to see if connectors may be loose, write
down the exact model # for when I go to the junkyard looking for a
replacement. (I wouldn't want to buy the wrong one...)

ECM on any make is usually quite reliable. Why do you suspect problems
with the ECM? BTW, I think this also controls the transmission. Is
that the reason? Have you checked the SL solenoid operation?

Ah ok.

I disabled my EGR system (again - last was disabled last year) and my
engine runs MUCH smoother now. (I decided against transmission
problems because when I throw the car into neutral, the car still
stalls.) I don't want to keep it disabled, but 1) I don't want to die
in traffic, and 2) taking the car to the dealer will just be too much
money, especially considering the car's 12 years old, and we'll
probably be buying a Sienna in January.

I'm suspecting the VSV, or maybe the throttle position sensor. My EGR
valve is clean, but maybe the spring is worn out...???

Stalls once a month or so, when warm, when approaching a stop. I
changed the EGR modulator last year, and that seemed to stop the
problems - but they've come back. ECT sensor also replaced earlier -
didn't help.

Thanks for the info re: ECM reliability - I thought a faulty ECM was
telling the VSV to do whatever it wanted...

Have you checked the basics?
Spark plug wires, coil, dist. cap, rotor, IAC valve, intake air hose
cracking, etc.?

Hi, Michael,

Just saw this on another group this morning:
Hey, every one. I've skimmed through all the threads posted and I have
not found a similar issue as this one. I'm working on my old boss'
2000 camry with the 2.2L engine and while she is driving it stalls.
I'm thinking that it could be a bad TPS. I'm leaning towards that but
I could be wrong. I have yet to look at the car. I was hoping that I
could get a heads up on what to test first. It's been a while since
I've had to work on a Toyota, besides my 97 Rav4, due to how reliable
it's been to me and all my friends that own one. I had a very similar
issue with my Rav, back in 2002, where it would stall once I came to a
stop. With no help from the dealer I was forced to delve into the
issue and I found that the TPS was at fault. I replaced the TPS and it
corrected the issue. Of course, I had to calibrate the TPS. This is
why I feel that it could be the TPS on this Camry. I could still be
wrong, though. I have till Saturday to get a response to this. Any
help is appreciated. Thanks.
===
Now when I cleaned the throttle body according to the Factory Service
Manual, I also followed their procedure using a thickness gauge and
checking continuity and break in continuity at the idle circuit
connections. So that may be something you would also want to check.
Perhaps the engine computer isn't receiving the correct signal to idle
when the throttle is fully closed. If it's only off by a few
thousandths of an inch, that might explain the intermittent nature of
the problem.

I actually replaced the air hose a few years back.

What would symptoms of a bad VSV look like?

Thanks,

Michael

Thanks! I'll look into the TPS some more...

Say- where do you get a thickness gauge? How much do they run for?
