1996 chevy 1500 5.7 4by4 have to new o2 sensor that i put on an there is a code that comes up as low circite bank 1 sensor 1 an then there is one for o2 sensor mulfuntion bank 2 sensor 1

This article will help you test the o2 sensor.

code p 0136 refers to heated oxygen sensor (HO2S) 2 bank 1 ---circuit malfunction===causes ---heating inoperative ---wiring---HO2S--- ECM
also refers to oxygen sensor (O2S0 2 bank 1---circuit malfunction===causes --- wiring---O2S ---ecm
it also refers to heated oxygen sensor (HO2S) 2 bank 1 ---no signal===causes ---wiring --- HO2S---
code p 0137 refers to HO2S 2 bank 1 ---low voltage -===causes --exhaust leak---wiring short to ground ---HO2S--- ECM
it also refers to O2S 2 bank 1---low voltage ===causes exhaust leak---wiring short to ground ---O2S ---ECM
to set you up here-- there are 4 oxygen sensors in the system
2 are heated oxygen sensors (HO2S) on in each exhaust manifold or exhaust pipe before the cat converter and
2 oxygen sensors (O2S) -- one in each exhaust pipe after the cat converters
heated oxygen sensors have 4 wires and O2S sensors normally only 2 wires
it is more that possible that you changed the wrong sensors and in the process damaged the delicate wires with the incorrect spanner being used

P1522 is not an O2 code in any Mazda model. Please go to this LINK and read about it.

The fault code P0135 means O2 Sensor Heater Circuit (Bank 1 Sensor 1)
The code P0141 means O2 Sensor Heater Circuit (Bank 1 Sensor 2)

Launch X431 Connector

Reset error codes by disconnecting battery for 5 minutes. Start fresh. all codes should be clear now. drive and see if any new codes come on. They are the ones you need to address.

157= 02 sensor ckt low volts 2/ 2 158=o2 sensot ckt high volts 2/ 2 159= o2s ckt slow response 2/2 181= fuel temp sensor a ckt rng/perform 327= knock sensor 1 ckt low imput bank 1 or single sensor 332= knock sensor 2 ckt low input bank 2

your code must be P0131, a P0131 code refers to the first oxygen sensor on Bank 1. P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.
The solution is you can:
1.Replace faulty sensor.
2.Repair short, open, or high resistance on o2 signal circuit. FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook

Code -P0146 - o2 circuit no activity detected,
Bank 1 senor 3
Bank 1 is going to be where number 1 cylinder is at,
It's going to be the very last o2 sensor on the exhaust pipe, check make sure it's connected, if it is more then likely bad sensor.

Your O2 sensor is starting to go bad .recomend replacement before it gets worse

p1133 - o2 sensor, Insufficiant Switching, Bank 1 Sensor 1.
p0131 - o2 sensor circuit, low voltage, bank 1 sensor 1
p0171 - Lean condition, Bank 1
p0300 - Random Misfire

I would be looking at the front passenger side oxygen sensor for issues. It may be bad, it may not be plugged in, bad wiring at harness.

The random misfire may be symptomatic of the o2 sensor problem.
