P0130 on Chevrolet
O2 Sensor Circuit Malfunction (Bank 1, Sensor 1)
P0130 on Chevrolet vehicles indicates o2 sensor circuit malfunction (bank 1, sensor 1). Au7o has documented this code across 1 Chevrolet model — most commonly on Prizm. This code indicates a malfunction in the upstream oxygen sensor circuit for bank 1, sensor 1 — the front O2 (or air-fuel ratio) sensor mounted before the catalytic converter on the side of the engine containing cylinder 1. This sensor measures the oxygen content of the exhaust so the computer can fine-tune the fuel mixture, and the code sets when its signal is missing, out of range, implausible, or not switching as expected. A faulty reading here can hurt fuel economy, increase emissions, and trigger the check engine light. It generally points to the sensor itself, its heater or wiring, or sometimes an exhaust/fuel condition the sensor is reporting. Typical repair costs on Chevrolet range from $100 to $300, depending on the specific model and root cause.
Common Causes of P0130
- •Failed or aged upstream oxygen / air-fuel ratio sensor
- •Damaged O2 sensor wiring, connector, or heater circuit
- •Exhaust leak near the sensor
- •Blown fuse or open in the sensor heater power supply
- •Corrosion or poor contact at the sensor connector
- •Vacuum leak skewing the fuel mixture
- •Contaminated sensor (oil, coolant, or silicone)
P0130 on Chevrolet by Model
Chevrolet Prizm(1 issue)
- Oxygen Sensor Failure1998-2002
Oxygen sensors fail causing poor fuel economy and check engine light. Both upstream and downstream sensors prone to failure. Oil consumption issues accelerate sensor fouling.

What does P0130 mean on Chevrolet?▼
P0130 stands for "O2 Sensor Circuit Malfunction (Bank 1, Sensor 1)." This code indicates a malfunction in the upstream oxygen sensor circuit for bank 1, sensor 1 — the front O2 (or air-fuel ratio) sensor mounted before the catalytic converter on the side of the engine containing cylinder 1. This sensor measures the oxygen content of the exhaust so the computer can fine-tune the fuel mixture, and the code sets when its signal is missing, out of range, implausible, or not switching as expected. A faulty reading here can hurt fuel economy, increase emissions, and trigger the check engine light. It generally points to the sensor itself, its heater or wiring, or sometimes an exhaust/fuel condition the sensor is reporting. On Chevrolet specifically, this code is documented across 1 model.
