I have a 2002 sonata 4 cylinder and got a computer diagnostics yesterday and it came up with 10 codes... P0103,P0750, P0755 and P0765 the others were repeats. I was told it is probably the ECM and I need to replace it. Can anyone help me with this, if I do need to replace it where can I find it. Thank you

 

The "07XX" codes, especially with 3 of them, likley lean on the internal harness to the solenoid set being at fault... this is the harness from the trans case to the solenoids..

The 0103,, MAF circuit problem... did you have MAF disconect with key on or running with connector unplugged ??

Replacing PCM be a total waste of money, likely harness issue inside the trans.

You do have an "AT" fuse in the engione compartment fuse block that supply source voltage to the solenoid set, pass through A/T first...

 

any idea what this might cost?
