P0134 O2 Sensor Code
Trying to get my 96 LT-4 back emissions compliant and I’m down to one code
P0134
Says that the Bank 1 Sensor 1 O2 Sensor isn’t responding, where is this sensor at?
Are there 2 or 4 O2 sensors on the OBDII Cars?
To be frank, I’ve modified the sensor to read a smoothed resistance so it doesn’t throw a Catalytic Cobb code...because my car doesn’t have Cats anymore.
The P0430 and P0450 (Maybe those aren’t exactly right) have gone away which to me means that both of the sensors I modified are functioning, and that there’s an issue elsewhere.
Any help is appreciated

P0134 : Heated Oxygen Sensor (HO2S) Circuit Insufficient Activity Bank 1 Sensor 1
LT4 has 4 Oxygen sensors. I really can't remember which side is bank 1, but I think it's the driver side. Front sensor 1 and rear sensor 2. Those plug-in connectors get hot, splashed and dirty down there. Mine was making poor electrical connection and just needed the plug cleaned out and the 4 wire connectors cleaned of corrosion. Put some silicone grease on the connector to help seal out moisture and it got well.
