I got a code 05 05, diagnose says that its not defined.
After that code, my car barelly starts up and rpms jump around. Sometimes they delay. Transmission shifts fine.
WHat could it be? Help
Thanks for any help

 

Reset the ECU propery.

 

I did reset the ECU, car still doesn't start wright could it be the air sensor or emisions sensor

 

i believe code 05 05 is the air intake temp sensor...though i never remember having any car trouble when i i pulled the code...its very likely that i am wrong, however if i was you i would still make sure that its plugged in properly...if you have stock intake it is located on the snorkel looking thing towards your resonator

 

emissions sensor wouldnt give you car trouble....its intake related

 

Are you sure you got 05 05 cause accourding to this: http://vbxmaxima.8m.com/ecudecoder.html
it means "No Failure Recorded/Detected"

 

05 05 means that the ECU detects nothing wrong with your car. Now obviously something is wrong, but it must not be something that affects the electrical system or can be detected by the ECU.

Now I got codes 03 04 and 02 15....could that be related? What should i do?

 

Yes i did it according to this

 

what did you do to the car?

 

Nothing actually, just driving it on the highway and the light went on. The next day it was difficult to start it.

 

Well that means you need to replace your knock sensor, but that shouldn't affect starting the car. I couldn't find 02 15, but I'm betting that is your major problem.

0304 is the knock sensor. 0215 doesn't exist! Are you sure it wasn't 0115? Problem with right bank fuel management system. Read the stickies!

 

I reseted ECU twice. After starting the car second time, a couple of minutes later the same codes came up. I'm positive that it was 02 15, because I wasn't the only one who was counting it.
The car drives fine, doesn't make any noise. RPMs act really weird though. Sometimes with delay, sometimes they jump up really fast after apllying barely any gas, and they drop down fast too after just letting of the gas w/o braking. It's hard to explain, but I know my Max well to see that there is something wrong.

What are the symptoms of knocking sensor going bad? Could that reflect it?

 

not sure if this can affect it but i could have sworn it did it to me. Check where u last put the screw on the ECu. I remember when i didnt fully put it counter clockwise, my rpm's were super low and jumpity....well super low from what i remember and could have been jumpity. Maybe u make a mistake and turn the screw clockwise after turning it counterclockwise...just a thought....

 

Code 0215 is P1446 "EVAP canister vent control valve closed"
Code 0304 is P0325 "Knock sensor or circuit fault"

I've got these from Haynes manual.

 

Code 0215 is P1446 "EVAP canister vent control valve closed" - What is that supposed to mean?
