3033R showing STOP, so it's running at reduced power. The code says 1209.04 - Exhaust Manifold Pressure Switch out of range - Low.
The Mode 1 ECU 047 displays 90.
I don't know where the pressure switch is located.
I don't know what to repair or replace.
Can anyone help? Thanks!

Thanks. The battery is fine, and I can't get the rid of the code!

Thanks for the post. I replaced the exhaust manifold pressure sensor and o-rings. It works perfectly!
