Hello,
I'm having multiple problems with my '96 Taurus and it hit me this morning that they all might be related. Note I know very little about cars, but am technically minded
- heater problems: I get hot air in vent mode, but not from floor - I changed the thermostat myself and it didn't seem to help.
- OBD code P0402 - EGR Flow Excessive
- OBD code P0761 - Shift Solenoid C Perf or Stuck
- OBD code (forget) - Oxygen Sensor - replaced myself - code stopped occuring - but started getting EGR code a few days later
I'm wondering if all or some of these could related and due to "low vacuum pressure". I thought the heater problem could be an air flap that is vacuum powered, the shift solenoid may be vacuum powered - hmmm
- by definition I guess a "solenoid" is electrically/magnetically powered, could EGR code be due to loss of vacuum? Thanks.
