Pre-97 B14 Emissions Questions
Have a couple of questions for you guys who have had your B14 apart a couple times and live in states which require OBD2 emissions testing.
- Does the pre-97 B14 have a EVAP pressure sensor?
- Does the pre-97 B14 anything else besides the EVAP vent valve for EVAP sensors/valves?
- I have read in the past that the 3 wire rear O2 will put out a different voltage than the 98+ 4 wire sensors, can anyone confirm this for me?
I'm sure I will have more questions once I dig further into this but the EVAP system on my P11 is causing me issues with passing emissions.
Is this pinout correct? I only see a EVAP vent on pin 116 and nothing else for EVAP.
