P Codes (powertrain)
P0100 - P0199
WHAT DO I DO WHEN THE CODE READS P0155?
1999 Chevrolet Astro
I have a 99 Chevy astro cargo van. The code reads P0155 - oxygen sensor heater, bank 2 sensor 1. Do I replace the sensor or is there a hidden issue that I need to take care of?

You need to verify powers and grounds to the o2 first. Then you measure the resistance across the heater portion of the sensor and make sure it is within specs.

I'm not a mechanic so how do I do that? Can you tell me step by step?

If you are not familiar with thw system and how it works, get some help as you need an ohm meter and a voltmeter, a wiring diagram and be able to acess the connector.
