hey i just need some help with 2 codes that came up - i did check them out and they are 02-10 which is ign sytem left bank:lean and 03-05 with is egr temp sensor -i replaced the temp sensor reset the ecu and the code still came back up ? i dont know what to do -with the other code i just ran a few bottles of cleaner thru it and that is still coming up -what do you think i should do? I cant pass inspection without fixing these 2 things and im past due on it already-any help at all will be greatly appreciated-also do you think changing the spark plugs will do anything ? thanks

 

I guess fix them the right way Just start with what the suggestions are

0210
Diagnostic Trouble Code 0210 points to a problem with the fuel injection system. When the engine management system is running in closed-loop mode the Engine Control Unit (the computer) makes continual adjustments to maintain the air-fuel ratio near the ideal point. To achieve this it relies on signals from many sensors including the Mass Air Flow Sensor and the Oxygen Sensors.

This malfunction is detected when the ECM finds that it cannot properly control the air/fuel mixture, and the mixture is too lean (too much air). DTC 0210 indicates this problem exists on the left bank (the front bank, cylinders 2, 4, and 6). Possible causes include ...
- Intake air leaks
- Front Oxygen Sensor
- one or more fuel injectors on the front bank
- exhaust gas leaks
- incorrect fuel pressure
- lack of fuel
- Mass Air Flow Sensor

0305
Diagnostic Trouble Code 0305 points to a problem with the Exhaust Gas Recirculation Temperature Sensor. This sensor is a thermistor (a resistor with a value which varies inversely with temperature). The EGRTS is used by the Engine Control Module to test the EGR system operation. Since the signal from the EGRTS is not used for engine operation your car should run perfectly well despite having the Check Engine Light on.

Possible causes of DTC 0305 include ...
- harness or connectors (The EGRTS circuit is open or shorted)
- bad EGRTS
- malfunction elsewhere in the EGR system

The EGRTS may be tested with an ohmmeter.
- at "D" degrees F the resistance should "R" (in Megohms) should be ...
D = 32, R = 0.68-1.11
D = 122, R = 0.09-0.12
D = 212, R = 0.017-0.024

 

yes i read that and i run nothing but 93octane and always have more than a half tank so that gets rid of lack of fuel or pressure unless its the pump -front o2 sensor is good b/c i replaced it when i put in my ypipe -do you think it is b/c i have a cai in the winter and it is sucking up to much cold air?

 

Do you let the car fully warm up for 15 min before getting inspection because the y pipe doesnt have pre cats in it but that wouldnt matter because you have cel but i wouldnt think it was the cai but why not try switching it out and see if that works the only 2 things i can think of is the MAF or intake air leaks.

 

thanks for the quick reply -anyone else have any ideas-im probably going to switch out the intake or atleast just take off the pipe so its like a pop charger with just the midpipe so the filter itself is atleast in the engine bay

 

ight well im going to put back the original intake setup 2m b/c i just found it -is there anything else that i should do while im there. just getting any other advice on what you think these codes could be. Do you think i should do sparkplugs while im actually not lazy and im doing stuff lol if so what kind of plugs do youll recomend and about how much are they?

 

You know the air sensor that in the snorkel? Did you pull the snorkel out and unhook the air sensor because if the sensor not hooked up it will throw a code I dunno if that any of those codes but that a possibility

 

hey i just wanted to bump this up for some more info -last week i took out the cai and put back on the stock intake -i thought it fixed it but i guess not-on the way 2 work 2day the light went back on with the same 2 codes-anyone else know what it is or have any ideas that i can look into-o yea and everytime the code comes they come up 2gether -does that have to do with anything

 

anyone have ne input at all? guesses

 

I have the same problem. I replaced the o2 sensor, but still got the code. I think it's the MAF.

 

thanks for the info blackmax yea i replaced my o2 sensors also maybe i will look into the maf -take it off and check it out-anyone else?

 

Do you have any rpm problems? Such as the rpms dropping big time when you let off the gas pedal while the engine is cold? That's the only other symptom I can think of right now that I have. Oh, I also replaced my fuel filter. And my engine will shut off sometimes when I step on the brake...

 

I'm going to clean my MAF.

 

Careful cleaning the maf, sometimes you can do more harm than good.
