What does a code p0134 on an oxygen sensor mean?
What does a code p0134 on an oxygen sensor mean?
A code P0134 may mean that one or more of the following has happened: Bad O2 (oxygen) sensor. Bad heater circuit in the O2 sensor. Wiring or connector to the sensor frayed / broken.
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.
Why is the oxygen sensor signal not detected?
Basically the oxygen sensor is inactive. Here’s why: The powertrain control module (PCM) provides a baseline voltage of about 450 mV on the oxygen sensor signal circuit. When cold, the PCM detects the the internal resistance of the sensor is high.
Why is the oxygen sensor on bank 1 inactive?
Although generic, the specific repair steps may vary depending on make/model. This code refers to the front oxygen sensor on Bank 1. Basically the oxygen sensor is inactive. Here’s why: The powertrain control module (PCM) provides a baseline voltage of about 450 mV on the oxygen sensor signal circuit.

What to do when the freeze frame code is p0134?
When the code P0134 is set, record the freeze frame data in fine detail. Next, duplicate the code setting conditions on a test drive, paying particular attention to load, MPH, and RPM. The best tool to use on this test drive is a data streaming scan tool that has factory quality, dedicated live data.
When did Bank 1 O2 sensor stop working?
I have a 2002 Chrysler T&C limited. In September 2012, squirrels chewed through the wiring to my bank 1 O2 sensor. After a quick and easy fix, there were no issues or codes. In February 2013, three error codes popped up (P0134, 0138, 0139), and the car was running sluggish and getting poor gas mileage.
