Description

OBD-II Trouble Code Description for P0134 Fiat

O2 Sensor Circuit No Activity Detected

What does this mean?

OBD2 Code P0134 Fiat definition:
This code definition: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. When cold, the PCM detects the the internal resistance of the sensor is high. As the sensor warms up the resistance is lowered and it starts producing voltage based on the oxygen content in the exhaust. When the PCM determines that the time it took for the sensor to warm up is greater than one minute or that the voltage is inactive (not reading outside 391-491 mV it views the sensor as inactive or open and sets the P0134 Fiat code.

Symptoms

Possible sumptoms of OBD code P0134 Fiat
One or more of the following may occur: Check engine light illumination Poorly running/engine missing Blowing black smoke Poor fuel economy Dying, stuttering

Causes

Possible causes of OBD code P0134 Fiat
A code P0134 Fiat 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 Blown heater circuit fuse Holes in the exhaust system PCM failure

Possible Solutions

The most common fix is to replace the oxygen sensor. But that doesn’t rule out the possibility of: Rusted exhaust pipe Inspect wiring & connector(s) for problems Excessive amperage blowing heater fuse (still requires replacement of sensor but also replacement of blown fuse) Replace PCM (only as last resort after all other possibilities are covered.

2. Look up the other OBD II Trouble Codes, please use the search box. Enter the 5 character trouble codes in the search box and submit the search.

3. Don’t assume a particular OBD-II code means the same for other auto manufacturers as there are many makes specific codes in use.

4. If your OBD-II trouble codes are for a different car, select that vehicle series before searching for the diagnostic codes because not all OBD2 codes used by one manufacture are used by the other makes.
