First thing to do, check your transmission fluid level. It might be low. If the scan tool is not communicating with the ECU, then you are not using the right scan tool. Your engine mounts might be bad.

erico2k2:

or someone tampered with the wirings of the ECU

anukulapo:

Is there an independent way to check if the ecu is still perfect so that we can consider the wiring.

sultaan:
You just bought the car or what

mayor2013:
Check the obd 2 connnector if all wirings are ok. If all is ok and current is getting there then am afraid your ecu connection has been re engineered aka coverted

erico2k2:

Yes do what mayor2013 adviced or better still, pull or disconnect one of your sensors ie CPS or O2 sensors see if it will throw a code
PS U need OBD11 scanner for this.

anukulapo:

Thanks. I will need get someone to do that for ne ASAP because I don't know how to go about that by myself.
If it is something simple enough, please guide me through. I will give feedback on the result.

mayor2013:


Do you have a multimeter?

anukulapo:

No sir but I can get to borrow one

mayor2013:


Can you differentiate between voltage, current, resistance, and continuity reason I ask is so as not to send a feed back voltage to your ecu there by getting it fried up

anukulapo:
Finally, we have been able to establish that the ECU has gone bad. Now the baby news is that the ECU number label has been peeled half way so that I can't get the complete part number.

How possible is it to get the right replacement through the new engine number?

Please advice.

Thanks.

This is not the ecu that came with the car.

GAZZUZZ:


If you install the right ECU, you will have to install the right engine. Long assignment ahead of you.

Post VIN, It Can be used to determine the right engine Ecu[/color]

Let me have the VIN of the car?

I am lost. From the VIN supplied, this is a 2004 camry. Four plugs. When I went back to read, the op mentioned that it is a 2002 V6.

Hello guys,

I am having trouble with my car. It started recently when I noticed that the car started jerking when shifting from gear 2 to gear 3. It was working fine all the while.

The scan tools that we have tried so far have not been able to communicate with ECU (it only reads the abs and airbag).

Upon close inspection, we discorvered that the engine in it has been changed to 2MZ (as against the 1MZ that came with it).
It's a 2002 Toyota Camry with a V6 engine

I don't know where to go from here. Please advice.

Thanks.

Good evening people. I hope your day has been fruitful so far.

I still look forward to your advice.

Engine is 1MZ. Matchable ecu; 89666-06251 to 257

anukulapo:

Thanks so much. I am grateful,God bless.

Information noted BUT I can confirm to you that the engine in it currently is 2MZ. Does it matter in anyway?
