OK. So I finally figured out how to get the Check Engine light after you fix the problem (disconnect the battery, thanks for saving me money guys heh), and realized the light wasn't goign out. So I took it in to have the codes checked again and the dealer said it was giving "implausible signal to EHA" or something, using a reference I'm assuming the real code was "current to EHA" because thats the closest match i could find on the list of codes.

Is there a common problem or malfunction that causes this code? Or am I going to have to get it fully diagnosed by my mechanic? I can fix most things if i know what to fix, so I would be saving a great deal of money if i could only figure out what was wrong.

Thanks for any help

EHA - Electro-hydraulic Actuator

 

The EHA is a fuel trim device mounted on the fuel distributor. It is one of the the few electronic servos of the KE injection system. The wires to the EHA might be frayed, or the EHA has an electrical fault and needs to be replaced.
