What is the code for bank 1 O2 sensor?
All our repairs are backed by our 12-month / 12,000-mile warranty. P0138 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream.
How to check OBD-2 sensor circuit no activity?
Visually check the Bank1,2 harness connector for melting or chafing of the harness or the connector. Repair or replace as needed 3. Turn ignition on, but engine off. Disconnect the O2 sensor connector and check for 12Volts at the Heater Circuit supply and for proper ground on the heater circuit ground circuit.
What is the diagnostic code for O2 sensor no activity?
P0134 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does the p0134 code on a knock sensor mean?
The P0134 code means that the air fuel ratio sensor is not operating. Most of the time it will need replacing to correct. The P0327 code means that your knock sensor is not getting enough voltage.
What does Bank 1 mean on an O2 sensor?
The Bank 1 portion of the code refers to the side of the engine with the number one cylinder (does not apply to engines with an inline configuration). Sensor 1 refers to the upstream O2 sensor (more about that below).
Where does Bank 2 go on an inline engine?
You can have bank 2 on both inline engines and transverse engines (engines mounted in the other direction). If you know which cylinder is number 1, it makes no difference if you have an inline or transverse engine. Bank 1 is always on cylinder 1 – 3 – 5 – 7 – 9 – 11 and bank 2 is always on cylinder 2 – 4 – 6 – 8 – 10 – 12. What is Sensor 1 & 2?
Visually check the Bank1,2 harness connector for melting or chafing of the harness or the connector. Repair or replace as needed 3. Turn ignition on, but engine off. Disconnect the O2 sensor connector and check for 12Volts at the Heater Circuit supply and for proper ground on the heater circuit ground circuit.
What does the code p0134 on bank 1 mean?
The code indicates that your car’s primary computer, which is often referred to as the powertrain control module (PCM), has detected inactivity from the upstream oxygen sensor (O2) on Bank 1. Inactivity from the upstream oxygen sensor can trigger code P0134.
