May 29, 2024 · Diagnostic Trouble Code (DTC) P0030 stands for “HO2S Heater Control Circuit (Bank 1, Sensor 1).” It may be triggered when your vehicle’s control module detects a fault in the heater circuit in oxygen sensor Bank 1, Sensor 1. Bank 1 is where cylinder number 1 is located.

Feb 18, 2022 · Diagnostic trouble code (DTC) P0031 stands for “HO2S Heater Control Circuit Low (Bank 1 Sensor 1).” This code is logged when the powertrain control module (PCM) detects that the actual and desired state of the oxygen sensor heater control circuit do not match.

Jun 2, 2016 · 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. Bank 2 is the opposite side of the engine. If you’ve got a four-cylinder, there will only be one bank.

To accomplish this the ECM (Engine control module) relies on the the Heated Oxygen sensors (HO2S). The HO2S detect oxygen content in the exhaust. This information is then relayed to the ECM. The ECM uses this information to adjust the fuel delivered to the engine.

Jun 2, 2016 · OBD II fault code P0031 is defined as “HO 2 S (Heated Oxygen Sensor) Heater Control Circuit Low (Bank 1 Sensor 1)”, with “Bank 1” referring to the bank of cylinders that contains cylinder #1 on engines with two cylinder heads, and “Sensor 1” referring to the oxygen sensor located before the catalytic converter (s), i.e., upstream of the converte...

Jun 8, 2024 · Diagnostic trouble code (DTC) P0051 stands for “HO2S Heater Control Circuit Low (Bank 2 Sensor 1).” This code is logged when the powertrain control module (PCM) detects a potential issue with the heater circuit for the oxygen sensor #1 on Bank 2.

Sep 21, 2010 · First thing to do would be to contact your Nissan dealer or the customer service hotline (1-800-NISSAN-1) with your VIN# and check for outstanding recalls and campaigns, as there have been a couple for your vehicle. If you're up to date, there was a TSB that addressed rough running and O2 sensor codes/MIL "on."

DTC P0031 means there’s a fault with the heated oxygen sensor (HO2S) control circuit 1, located on the exhaust manifold before the catalytic converter. “Bank 1” indicates that the sensor is on the engine side with cylinder #1.

Feb 22, 2024 · To troubleshoot the P0031 code, you may need to use a multimeter to test the resistance of the HO2S and the wiring harness. You may also need to check the fuses related to the HO2S circuit. If you are not confident in your abilities to diagnose and repair the issue, it is recommended to seek the help of a professional mechanic.

Mar 23, 2024 · 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 takes the sensor to warm up and start sending an adequate signal. The code is set when the sensor is taking too long to warm up.
