It is located behind the passenger side kick panel beside the glove box. It will have the exact part number you need on it for your engine/trans combo.

The only place to get it would be online, dealership or a salvage yard. Here is a good place to check once you have the part number: https://parts.lakelandtoyota.com

Why?

The ECM can be damaged, but it's usually the last on a long list. The FSM diagnostics were written for brand-new vehicles. In that case, after checking a slew of other candidates, the list would end with "replace the ECM." Once your vehicle hits, oh, 24 years, a failure in the wiring, connectors, components is much more likely.

mechanic told me that is the code that came up

replace ECM

no other codes came up

i am no mechanic ..thats why im here

he has 30 years or more with yota issues

is he wrong??

code wrong?

just need it fixed

thanks again

Was it code 11? I'm not sure with the 22re, but as far as I know that doesn't mean you need a new ECU. Could be interruption of power supply to ECU, or throttle position sensor. I'll let someone more familiar with the 22re chime in.

michael1952

appreciate any help

...TPS checked out ok..........MAF also...cleaned throttle body

cleaned injectors

has new plugs/wires/distributor

What exactly is the truck doing?

michael1952

it may run fine for a day or two..then

starting of at stoplight/stop sign/dead start ..it just has no power...engine doesnt cut ofd

have to baby gas pedal to get some RPMs....then takes off,

doesn't spit and sputter on highway..plenty of get up and go

when it does have the issue, engine shakes...black smoke out of exhaust the smooooooths out...IDK

mechanic had to drive it 2 days before it finally did it

thanks

Has the TPS been adjusted properly? That sounds like a possible cause if it tested good. Did he remove it to test? It can't be thrown back on without adjusting it properly.

Knowing what code it's throwing could help too. If you don't remember you can check yourself. Jumper TE1 and E1 in the under hood diagnostic connector, turn key to "on" without starting and count the flashes of your check engine light. Long pause between codes, each series of blinks is a code.

Here's the list of codes, and how YOU can retrieve them. http://web.archive.org/web/201410310...26diagnosi.pdf The only code for which the "only" suggested repair is "replace ECM" is 53, and I really, really doubt you have that code.

As I mentioned, each code has a list of causes, ending with "ECM" once you've eliminated all other possibilities. I don't have a lot of confidence that you've eliminated all other possibilities. In which case, replacing your ECM will not help.

michael1952

just verified CODE 11

scope103

By reviewing the FSM, what does that tell you?

michael1952

TPS has been eliminated it checked good

see code 11

later 22re engines

But was the TPS tampered with? If it was it need to be adjusted.

michael1952

it 9the TPS) was checked and verified it was set correctly yesterday

at this point really tired of screwing with it after months of dealing with it

autozone can get me ECM...and said i can return if it doesnt fix problem

mechanic gonna install and make sure adjustments are correct with it

every thing else mentioned above as to what could be the problem checks out to be good

thanks for all the help...........

michael1952

Im baaaaack...replaced ECM at considerable expense same problem different day...

at the end of my rope......

Im listening

picked it up...ran fine for few miles...slowed down to make a turn..geared down then started accelerating

spitting and sputtering..til i babied the gas pedal to get rpm s up

the wife was behind me,,,,i asked her if black smoke was coming out tailpipe and she said yes

Code 11...

TPS even though it checked ok???

whats left???
LOSS OF POWER SUPPLY TO ECU

--IGNITION SWITCH/CIRCUIT

--MAIN RELAY/CIRCUIT

--ECU

First you have to verify the source... is it fuel?
Is it ignition/ fire?
then you can start the process of diagnostics and elimination of possibilities...
eliminating 1/2 of the possibilities is huge... fuel or fire?
this sounds like moisture in your distributor...
Check and see if your distributor cap has the oring to keep out moisture...
it doesn't have to be WET just moisture REALLY causes some trouble especially at idle... or low rpms... clears up when it dries out then does it again when contaminated

michael1952

coming to work at 6 am today.....ran fine for 15 miles.....

then..i can tell its starting to do the problem described

i ease off gas til i feel it go away and all is good again
