I bought and installed a new airvalve today. Sadly the DTC returned. Any other ideas?

P0803 DTC back
The P0803 DTC reared it's ugly head today. Before reseting it this time I took off the hose that goes to the throttlebody on the airbox and revved the motor. The butterfly sat lifeless. I then reset the DTC and repeated reving it and it moved! I still have no idea why the computer reports it as a 1-4 shift solenoid malfuntion but I think I am getting close. Any further ideas?

Could'nt I just command the solenoid manually using a scan tool?

I took it to a shop and had them try and manually trigger the solenoid. They confirm it works only some of the time. $30.00 part later I hope it fixes it! I will know more on Monday.

I'll check. Supposidly all that is required is dropping the valvebody located in the trans pan area and replace it.

Just got a call from the shop, it WAS'NT the solenoid. It's not the EGS, but rather whatever controls that. They had a new EGS and tried that but it performed the same. Now they are literally going wire by wire to find the problem. I did'nt know this car used a C.A.N. system bus, pretty advanced for 1998!
