96 or newer we have here, care to tell displacment too? 1.6 or 1.8 ?
Heinz 57 varietes on kicks. (no joke world wide)
for get dupicates. just a scanner hickup. (or is it pending versas set)
p0136, heater bad rear oxygen sensor. ( believe it.) new rear sensor needed .
p0740, Torque Converter Clutch Circuit Malfunction TCC is slipping or other related.
p0400 , EGR monitor failed. I think this is real. clean it and the whole EGR path.
the tcc is the most complex.
can be just you were driving funny and fooled it.
or TCC is bad.
TCC relay is bad, or TCC solenoid in tranny is bad , wiring to each and other serious tranny problems ( automatics are complex and can be a real pain to diagnose)
click my sig link then egr dreaded link.
the scanner shows HARD fails and Pending, they are all probably real.
Pendings are just below the legal EPA limit. nothing more.
In the manual they say fix the primary fails first and then others can go away by self.
in your case oxy heater is real , it never gets that wrong, it can see the heater is open circuited !
the TCC , Id just just go for a Tranny full flush and pray.
EGR> on this car 96 or newer , the EGR monitors are very accurate , unlike the older.
it is more sensative but more accurate. I'd believe it.
but for not I recommonded , making sure it is not stuck open.
failures of EGR:
1: stuck open and can really messup drive-abillity and power.
2: clogged completely anywhere in EGR exhaust path.
3: partial clog , on same #2 path. see EGR tube , see where it goes to Plenum , it will be clogged there too. (or reduced)
