so, had a mishap with some road debris, and it affected and shorted out the O2 heater circuit on my obd1 P72.

i have tested all wires, and it it pointing towards the heater circuit in the ecu as being bad.

is this repairable, or is the ecu now junk?

also - if i were to want to chip this with a hondata s300 (which can disable o2 heater from what i have read) will it still be a useable ecu?

yes - i googled, and came up empty.


thanks.

 

so, no one else has every had this issue or knows anything about it?

google has lots of threads about the ecu circuit burning up, but tells me nothing about what actually burns up or how to repair it...
