before you replace anything else, scan the engine for trouble codes if you have no codes present (not likely) check for fuel pressure and exhaust flow

First get a readout of the trouble code. Any mechanic, or Autozone in the US, can do this.

Then look up a chart of codes for your car. They don't change much year to year.

what engine, what size. that is first question.
misfire, map ,maf, iat, ect,tps and cat fail and low coolant temps.
very odd mix there. did you pull connections, key on???????

it means they all fail a test.
DIY? or just curious?

the question is , which is the most important.
all are cept 420, (last that, and bet goes way. later.)

reset the ECU, and see which come back.?
check all fuses.
then post codes that repeat, after fuse checks.

does the engine get fully hot running, 180F minimum?

Remove the EFI fuse for 10 sec or more with the ignition off. It is in Junction block 2 in the engine bay.

The trouble code will return if the fault still exists despite repair procedures.

first the quest, this is common for nissan, replace the knock sensor, this sensor is located under the intake manifold rear of engine, some models you can sneak sensor out without removing the intake, this will take care of that car. now the camry, im guessing this is a 4 cylinder engine, replace the air fuel sensor (oxygen sensor) thats on the exhaust manifold. this will solve that problem. hope this helped.

Here's a link to the Camry color codes:

It has a trouble code, you need to have it scanned. The light will flash the trouble codes if you jump terminals E1 and TE1 in the diagnostic plug.

The 1st thing to do is have a trouble code retrieval test run to see what is making the check engine light come, this is the source of the problem.
