O2 sensors, obd2 voltage
Hi!
First post here (tried to search + google but cannot find...)
Background:
Bought 350z for a project car and got multiple lambda codes. Car had both rear o2 sensors and bank 2 af sensor replaced + bank1 cat but previous owner never got broblem solved. Car has oem widebands at front so it is "2004.5". I found from threads that when using generic OBD2 reader, A/F sensors are scaled to display voltage like standard o2 sensors and bank 1 shows half compared to bank2.
Question:
-What is exact (obd2 scaled) voltage of front a/f sensor at stoich? (14,7AFR)
-What is exact voltage of rear o2 sensor at stoich? (14,7AFR)
Meaning, obd scaled (PID), not ones is service manual
This info would help to diagnose my broblem
