Can anyone tell me what the codes mean and how to repair or if they need to be replaced. These are the codes the obdII gave out P-1000=OBDII Sysytem check incomplete????P-1518=IMRC Stuck Open...where is this valve located?.....P-1780 Transmission Central Switch Out of range..what the heck does that mean? and where is that thibg suppose to be located? Once again any and all help will be appreciated.

 

Looks like you recently disconnected the battery.

Until the P1000 code goes away I wouldn't worry about the other codes just yet.

 

i havent disconnected the battery lately or even recently......how can i have that p-1000 go away or can it be reset?..oh yeah the car runs good other than the valves pinging..only thing i did to it was replace the spark plugs and wires and change the oil and oil filter

 

Did this just start after you did the work?

 

plug the code reader back up, clear the previous data, and read the computer again.

as far as the imrc, seems like those things are becoming a bigger problem than help. the imrcs are located in the lower intake. if i had to guess, id say one of the arms on the back of the intake that controls them has broken. its not easy to get to, but its possible. take off the upper intake and look on the back of the lower. there will be a black box with and arm on each side connected to the intake. make sure they are still connected and havent broken off.

good luck

 

would u happen to have a pic of both the upper and lower intake?

 

i might have one around here somewhere...let me check
