#9 of 80 2003 Chevy Blazer

I just recently got my service engine soon light coming on. I thought originally it was bad gas because it was right after I got gas, within 15 minutes. After my store stop I added the same amount of gas from a different station. Light stays on. runs ok. Is there a manual way to get the codes on this vehicle or do I need a reader. I know my other vehicles you had to do a succession of key off etc. I would appreciate any help.

No, need a code reader and Advance and AutoZone read for free as well as many other local stores (in hopes of selling you parts). Read it out and maybe just a simple loose cap so write the code down and have them erase it and see if it returns.

Does anyone know what this code is or where the sensor is located? My Chilton is worthless!

O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
Probably in exhaust pipe just behind the converter.

I am working on a 2000 chevy Blazer and the error code that came up was P0147. It says that it is an oxygen sensor. Does anyone know what (out of 3) oxygen sensor this may be? Thank you in advance.
#16 of 80 2002 Chevy Blazer Oxygen Sensor Replacement
Dec 04, 2007 (10:15 am)
I recently had my check engine light come on and upon checking it with a pocket scanner came up with a DTC P0155 (O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1). My Chilton Manual says my 2002 Chevy Blazer 4.3L V6 has more than one oxygen sensor. My questions are
1. Is this the sensor located on the exhaust pipe near the catalytic converter?
2. Is this difficult to replace?
3. Any tips to make the job easier (special tools, etc.)

Hi Lance. I think you are right about the sensor location near the converter. I usually go to Auto Zone for diagnosis and parts. They can tell you exactly where it is located and the part is about 1/3 of a GM replacement sensor. I buy Bosch replacements for my 96. It's a simple job. Just unplug it from the wiring harness and use an open end wrench. Start it up first and let it run for a couple minutes before changing the old one. This helps break the old one loose. Don't run it too long or you'll burn yourself. The new sensor usually has anti-sieze already applied to the threads. If not buy a small tube. It makes future replacement much easier.
If you have a set of ramps you can drive up on them for easier access. I usually don't use them and don't have a lot of trouble if I suck my belly in.
