How to fix P0030 code?
To fix this, check for any blown fuses and disconnect the oxygen sensor connector. Using the voltmeter, with the engine off, check whether there’s a 12V fused battery feed to the heater element. If you see no voltage, then repair the short or open in the B+ feed circuit.
Can am P0030 code?
Code P0030 stands for Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1). This indicates the PCM has detected a problem with the bank 1 oxygen sensor. Bank 1 refers to the side of the engine that has the #1 cylinder.
What happens to the fuse box on a Volvo XC90?
* Please be aware that if these fuses are not intact, or have been removed, the alarm will not sound. WARNING: Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
What does the code mean on a Volvo p0030?
P0030 VOLVO Tech Notes. The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it take the sensor to warm up and start sending an adequate signal. The code is triggered when the sensor is taking too long to warm up.
Why is my oxygen sensor blowing a code?
The code is triggered when the sensor is taking too long to warm up. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.
How does a heated oxygen sensor work in a Volvo?
P0030 VOLVO Description Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches that temperature the faster the sensor will start sending an accurate signal to the Engine Control Module (ECM).
