memory codes:
33 - EGR valve closed/erratic or has insufficient flow
53 - Throttle Position Sensor voltage is too high
KOER codes:
12 - Cannot control RPM during self check Idle Speed Control Problem
23 - Throttle Position Sensor is out of range
11 - System Pass?

 

if you still have egr and not deleted it then the code 33 could indicate a few things= possible bad egr sensor or valve is stuck closed....or the egr ports/exhaust cross over in the heads/intake are plugged with carbon......easy way to test egr is apply vaccum to valve while car is running and see if motor begins to run rough or die..as for the tps sensor ...you'd need a multimeter to check the vref circuit on it and make sure there is a ref voltage of no more than 5 v present then prob the signal return and monitir the voltage sweep while slowly opening the throttle and look for any opens or shorts to ground....or simply replace the tps sensor and set it to .75 to .99 volts and be done with it and clear codes and rerun koer test...as for idle speed prob......are you having idle issues??

 

yea it idles around 2,000

 

how do I set the volts on the TPS

 

I just replaced the TPS and scanned again came up with this.

KOEO And Memory Codes:
11 - System Pass?

KOER codes:
12 - Cannot control RPM during self check Idle Speed Control Problem
91 - Exhaust Gas Oxygen Indicates system lean bank 2 or fuel pressure out of range or fuel control circuit failure

 

if you have an idle issue that high ..sounds like the Iac pintle is either stuck or the IAC has failed either try cleaning it and or replace it and make sure the Iac passage on the intake is free and clean of carbon..do that and rerun test and see if idle can then be controlled as for lean condition...make sure there are no exhaust leaks on bank 2 before o2 sensor= drivers side..if none exist try replacing o2 sensor for a quick fix..and rerun test

 

I actually have an exhaust leak pretty bad, i just replaced the passanger side rear tire and i noticed the muffler is crushed. A few weeks ago I hit a man hole on a road that was being torn up and it caused the leak, but I didnt even notice the extent of the damage b/c I stopped driving it.

I replaced the TPS (still didnt really set it to the correct voltage but I played with it till is sounded good) and it no longer idles at 2,000 its at 1,000. Still have the same codes but now I know I need a new exhaust.
