LT1 / TH400 Stuck in Open Loop

[dave w]

I'm thinking the reason the LT1 / TH400 is stuck in Open Loop is due a faulty O2 sensor or sensor circuit (error code 63)? See attached files. Maybe there are other reasons the LT1 / TH400 is stuck in open loop, but error 63 needs to be fixed before going any further?

Currently the .eedata file format is not recognized. I'll need to ping 1project2many to update .eedata as downloadable files.

i think you can .zip files here, can't you?

[steveo]

yup. so just zip your eedata. a good idea anyway since it's not a compressed format, it can be way smaller once you zip it.

It does goes to open loop if the DTC is set.
Here is some info that might help you for quick fix.
