Could be EGR Valve.
A HO2 sensor (heated oxygen sensor) moniters the level of oxygen in the exhaust and sends that information to the engine control module.
On the Minivan it is the sensor in the exhaust on the back of the engine in the exhaust manifold.On an Intrepid/LHS/Concorde it is the pass side above cat oxygen sensor.On the Minivan it is the sensor in the exhaust on the back of the engine in the exhaust manifold.On an Intrepid/LHS/Concorde it is the pass side above cat oxygen sensor.
Exhaust
The EGR (Exhaust Gas Recirculation) valve position sensor monitors the position of the EGR valve, which regulates the flow of exhaust gases back into the engine's intake manifold. By providing real-time feedback to the engine control unit (ECU), the sensor ensures the valve opens and closes at the appropriate times for optimal engine performance and emissions control. If the sensor malfunctions, it can lead to poor engine performance, increased emissions, and potential engine damage.
They should be in the exhaust system close to the engine ( either in the exhaust manifold outlets or the exhaust pipe ) before the exhaust enters the catalytic converters Bank 1 is the passenger side of the engine and sensor 1 is the upstream sensor Bank 2 is the driver side of the engine and sensor 1 is the upstream sensor on that side
Bank 1 is the drivers side of the engine. Sensor 1 will be the first sensor that is screwed into the exhaust pipe that is the closest to the engine/exhaust manifold.
This light usually indicates an emission control issue. In most cases it is due to the oxygen sensor in the exhaust.
That is the O2 sensor in the exhaust closest to the engine.

The hego sensor, or heated exhaust gas oxygen sensor, is typically located in the exhaust system of a vehicle. It is usually positioned before and/or after the catalytic converter to monitor the oxygen content in the exhaust gases. This information helps the engine control unit (ECU) manage fuel injection and maintain optimal air-fuel ratios for efficient combustion and emissions control.
