Good day! Having a hell of a few weeks trying to fix my suv to pass emissions. First replaced the bank 2 sensor 1 a few months ago. Light came bank on for bank 2 sensor 2, fixed that. Light immediately came back on for sensor 1 again.. Took it to a highly recommended shop this time and they said it needed to be replaced AGAIN, basically the other mechanic screwed it up and another new part (costing twice as much as first one) needed. So, bank 2 sensor 2 replaced twice. Thought I'd be good to go, but no. Now there's a PA03? code. Something to do with range performance. They checked for
Hello. The code you have provided is not a valid automotive error code that I recognize. Based on your context I think it may be possible that there is an issue with the signal range of one of your oxygen sensors. If you’ve replaced the sensors then perhaps the issue may be with the wiring. I would carefully examine the wiring to the oxygen sensors, as well as the connector and contacts for any signs of damage, wear, or corrosion. If the sensors and wiring all check out then it may be possible that the issue is with the computer.

Can I Still Drive with a P2A03 Code? The P2A03 code will not immediately present your car with conditions that make it inoperable. However, continuing to drive your car in a potentially rich or lean running condition can cause severe damage that could lead to significant repairs.
The P0130 code is an OBD code that is triggered when the Engine Control Module (ECM) fails to detect any activity from the oxygen sensor that is located on the Bank 1 side of your motor and exhaust system.
Yes. While the damage may seem small initially, the longer you drive with a bad oxygen sensor, the worse the damage will become. Eventually, you may experience rough idling, poor acceleration, engine misfires, an illuminated check engine light, and failed emission tests.
Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter. If either the oxygen sensor in the cylinder block or the one for the catalytic converter fails, your vehicle could experience serious engine problems.
The O2 sensors are mounted in the exhaust system of the car, with Sensor 1 located before the catalytic convertor. Sensor 2 is mounted in the exhaust stream and is located after the catalytic convertor.
Code P0420 indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by the vehicle.
P0131 O2 Sensor Low Voltage Bank 1 Sensor 1 — What It Means
In this instance, Bank 1 Sensor 1 would mean the sensor closest to the manifold, on the driver`s side cylinder bank of a V6 or V8 engine. The signal from the O2 sensor is used to determine fuel metering and ignition timing.
Bank One is always the bank where cylinder number one is located. On the Corvette it will always be the driver side. Bank Two is the passenger side. Sensor 1 on Corvettes is always the sensor that is closest to the exhaust port of the engine.
On most in-line engines, the Bank 1 sensor 1 will be located at the engine`s front side, near the cylinder head. On most front-wheel-drive models with V6 engines, this sensor will be on the backside against the firewall. Most rear-wheel-drive cars and pickups will have this sensor on the passenger side.
What the P0430 code means. The P0430 code is set when the ECU detects below threshold performance from the catalytic converter. The ECU monitors the catalytic converter closely and when a the low performance threshold is detected the Check Engine Light will be displayed on the dashboard.
Oxygen sensor failure can often be traced to one of three common factors: Age and high mileage, an internal contaminant (poisoning) or an electrical issue. One or two wire unheated oxygen sensors should be inspected or replaced every 30,000 miles.
Can I Drive My Car With A Bad Oxygen Sensor? We recommend against driving with a bad O2 sensor as the powertrain is not running on the correct fuel mixture. While it may perform fine in the beginning, if your engine is running rich and using too much fuel it might begin to clog the catalytic converter.
Generally, oxygen (O2) sensors last about 30,000-to-50,000 miles if you have an older car. Newer sensors can go 100,000 miles before they need to be replaced. University Auto Repair lists six signs below that your vehicle`s oxygen sensor is dying.
A P0420 code is set when the upstream sensor and the downstream oxygen sensor sense the catalytic converter is not doing its job. Basically, the amount of oxygen going into the converter is not being burned, and it detects it through the downstream sensor.
Generally, when the check engine light comes on, it means that your vehicle`s emissions system is not working properly. One key reason the light goes on is due to an oxygen sensor malfunction.

A P0420 code indicates that your vehicle`s computer (PCM) has detected a problem with the catalytic converter. The catalytic converter`s function is to break down dangerous pollutants produced during the combustion cycle, lowering emissions released through the exhaust pipe.
