tome8689 Posted November 9, 2006 Share Posted November 9, 2006 My son is at college and had the check engine light come on his 2003 Accord EX. He called Honda and of course they wanted $85.00 to check the computer for the code problem. He went to Advance Auto Parts and they hooked it up and got the following reading: P0141 O2 Sensor Heater Cicuit Malfunction (Bank 1 Sensor 2) When he called the dealership they told hime it would run about $450.00. He doesn't have that kind of money so I was wondering if this code is for one or both of the O2 sensors and if they are are they that difficult to replace. Thanks for any help you can give me.

Nancy Posted November 9, 2006 Share Posted November 9, 2006 o2 sensors arent difficult to replace. id replace both of them at once. just unbolt them, unplug them and then replace them with the new ones. dealerships always try to ass rape you with the prices, mostly for labor. just go to your local autoparts store and you can get the o2 sensors for way cheaper. once you have the new sensors in be sure to disconnect the battery at least for 30 seconds and reconnect it, that resets everything.

cranny Posted November 9, 2006 Share Posted November 9, 2006 the code should be specific about which O2 sensor is bad , primary or secondary , if honda tells you they dont know which one , there liars. Link to comment Share on other sites More sharing options...
Kastigir Posted November 11, 2006 Share Posted November 11, 2006 When buying new O2 sensors, it's best to go with what came in your car. Go to sparkplugs.com and find your model. I recommend the Densos. Link to comment Share on other sites More sharing options...
