Code P0134 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

gchemist · 07-13-2011, 12:33 AM

My Jimmy has an intermediate P0134 code. If I leave it alone, the light turns off. All four O2 sensors are new. I'm going to move the reat cat O2 sensor to the Bank 1 Sensor 1 location.

Potential Symptoms
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 for 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
Blown heater circuit fuse
Holes in the exhaust system
PCM failure

Has anyone had this problem? I wonder if low fuel pressure can cause this code?
