Means sensor 1 bank 1 no activity detected.
WHat is happening is the ECM thinks the sensor is hooked up but is not getting a reading from the sensor.
So the sensor is:
Bad
Is actually unpluged because the ECM can't tell the difrence.
Has a broken wire in the harness.
I have seen the Sensor has rotted out of the pipe and is hanging on the wires.
Trouble code P0134 means:O2 sensor circuit no activity detected (Bank 1 Sensor 1)
Trouble code P0134 means:O2 sensor circuit no activity detected (Bank 1 Sensor 1)
Trouble code P0134 means: HO2S (Bank 1 Sensor 1) Circuit No Activity
Trouble code P0134 means:O2 sensor circuit no activity detected (Bank 1 Sensor 1)
Trouble code P0134 means:O2 sensor circuit no activity detected (Bank 1 Sensor 1)
Trouble code P0134 means:O2 sensor circuit no activity detected (Bank 1 Sensor 1)
Trouble code P0134 means:O2 sensor circuit no activity detected (Bank 1 Sensor 1)
o2 sensor
P0134 - 02 (oxygen) Sensor Circuit No Activity Detected (Bank I Sensor 1)A code P0134 may mean that one or more of the following has happened:Bad O2 (oxygen) sensorBad heater circuit in the O2 sensorWiring or connector to the sensor frayed / brokenBlown heater circuit fuseHoles in the exhaust system (between engine and cat)PCM failure
Trouble code P0134 means: HO2S-11 (Bank 1 Sensor 1) No Activity Detected Trouble code P0154 means: O2 Circuit No Activity Detected (Bank 2 Sensor 1)
P0134 = no activity detected on the O2 Sensor, front pre-cat. Symptoms include rough idle/stalling & lousy fuel economy.
