I diagnosed my car today to see why the light is on (first time since engine swap) Here is what I got.... ****KOEO**** 23-TPS out of range -I guess I need to check the voltage with a Multimeter...and maybe replace it.... 51-Collant Temp high voltage or open circuit 81-Air managment system 2 or inlet Air control fairlure or boost pump fail -What is that? 82-Air managment system 1 or inlet air contrl cirsuit failure -????? 83 EGR control vent circuit failure or electro cirsuit failure or low speed pump failure -I remvoed the EGR and I thought it shouldnt be a problem? 84-EGR vacuum solenoid or vacuum regulator shutoff solenoid failure -Probably has to do with the EGR delete 87- Fuel pump primary circuit failure or temp. compensated pump solenoid out of range? -Huh?...fuel pump works... ****MEMORY CODES*** 22-Manifold Air pressure or Baro snesor is out of range... -Bad MAP or vacuum leak maybe? 51-Coolant Temp snesor again... ****KOER**** 21-Colant temp.... 22-MAP sensor out of range 25-Knock snesor not found (not there...lol) Sooo...I guess my main concerns are with the coolant temp (seperate thread)...MAP sensor...the 81 and 82...is that EGR stuff? Is the EGR delete going to affect engine performance? And lastly the fuel pump code....what the heck is that? Thanks for looking and sorry for any mispellings... -Teddy Gram
did you perform the diagnostic test with the engine at normal operating temp.or cold if you did this cold that would be the reason for most of the codes that showed up
