[Shotimes] 93 ATX codes

[Steve Weinrich]

The "33" codes are actually a "111" twice.  Means no errors from that
section of the test.

163 - ???? Can't find.  Maybe a 173 which is a HEGO code for the RH sensor.

332 - Either a set of clogged intake nostrils on the intake or some other
problem in the EGR and sensing circuits.  For a diagnostic procedure, check

00004

543 - Don't worry about it.  Usually comes from stalling the engine,
especially on an MTX.

632 - Either you didn't push the OD cancel button during the prescribed time
interval or the switch/wiring is defective.   Does the O/D light on the dash
go on and off?

Good luck and verify that first code.
