The oxygen sensor on a Saturn can be found in the exhaust manifold at the front of the engine. It simply unscrews and unplugs.
5 minute fix!
The B1 S2 is located in the exhaust system from the drivers side of engine after the catalytic converter.
No. Fuel mixture and start up is Dependant on other sensors ECTS, IAT, MAP, and CPS. A no start situation may be the cause of a bad ECTS as this is most common. Replace with brass ECTS.
No activity from B1 S2 O2 sensor circuit. Check O2 harness and connecter for damage. If harness and connecter look good replace faulty B1 S2 O2 sensor. This is the sensor after the B1 catalytic converter (AKA downstream O2 sensor). B1 (Bank 1) is the bank of cylinders that contains the number one cylinder.
Tunnel B1 - 1996 VG is rated/received certificates of: USA:K-A
O2 Sensor (B1 S1) Voltage High
P0137 = O2 sensor circuit low volts (bank 1 sensor 2). Could be a faulty B1 S2 O2 sensor.
P1131 = Insufficient switching O2 Bank 1 Sensor 1 Sensor/lean. Could be a B1 S1 O2 sensor going bad.
B1S1means...B1 means the side of the V6,V8,V10 engines where is situated the number 1 cylinder. B2 means the other side of the V6, V8, V10 engine. On straight line engine they only use B1. S1 means the sensor upstream or before the catalyst converter and S2 means the sensor after the catalytic converter.
Trouble code P0138 means: O2 (B1 S2) Sensor Voltage High Condition
The b1 s1 O2 sensor on this model is located on the firewall side of the engine. I just changed mine, I couldn't get to it when it was on a lift so I went from the top. Not easy but very doable.
B1 in science is you and genes
"=((B1-A1)/B1)*100" alternatively if you format the cell as a %, it would just be "=(b1-a1)/b1"
