98 chevy s-10 codes p0131, p0171, and p1133

Error code P0131 is described as O2 Sensor Circuit Low Voltage Bank 1 Sensor 1. This indicates there is a problem in the wiring, such as corrosion, breaks or separation.

there are about a dozen O2 sensor codes. Tell us which one you have

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.

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

P1133 indicates heated oxygen sensor insufficient switching bank #1 sensor #1. P0131 indicates voltage from that sensor is staying low more than 2 minutes. That sensor could be bad or it could indicate a rich condition.

From what I can find in my book - they are (generic code)
P 0700 Transmission Control System Malfunction
P 0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
P 0137 O2 Sensor Cicuit Low Voltage (Bank 1 Sensor 2)
P 0131 O2 Sensor Circuit Low Voltage (Bank 1 Sensor)
P 0171 System Too Lean (Bank 1)
Could not find these codes in the GM section - that is why I went with the Generic codes

p0171-System Adaptive Fuel Too Lean

p0401-EGR

p0452-EVAP Fuel Tank Pressure Sensor Low Input

p0131-Upstream Heated 02 Sensor Circuit

Hope That Helps.

P0131=O2 Sensor Circuit Low Voltage Bank 1 Sensor 1
P0151=O2 Sensor Circuit Low Voltage Bank 2 Sensor 1
Marc,
this shows that the oxygen sensor on the left exhaust pipe before converter is bad,
And the front oxygen sensor on the right exhaust infront of converter is bad.

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.
