My 99 3.8L Convertible failed somog yesterday. The emissions were OK, but the MIL light is inoperative. In fact I get NO lights any time other than ABS, Airbag and Seat Belt on start up.
I have a traction control switch that seems to do nothing, and the Over Drive switch on the shifter does nothing.
I checked all the fuses. All OK. I checked the instrument cluster lamps, all OK. Connectors and wires seem OK.

The OBDII codes read
P0443 Evap Purge
P0412 Secondary Air Injection
P0141 O2 heater
P0161 O2 Heater
P0135 O2 heater
PP0155 O2 Heater
P1451 Mfr Code
P1409 Mfr Code

Is this a PCM issue, or is there some other cause?

Has anyone else had this problem?

TIA
Scott
