Question about 2003 Honda CR-V

1 Answer

I have been getting an intermittent CEL on my 2003 Honda CRV for a couple of weeks now. I took it to AutoZone when the light was on and it showed a P0134 code with the following definition: A/F sensor 1 heater system malfunction Probable Cause: 1) Open or short circuit condition 2) Poor Electrical Connection 3) Faulty A/F sensor 1 Of course AutoZone wanted to sell me the $200 non-refundable sensor right away- is there anything else I can check first?

If you have a scan tool that shows sensors, you can clear codes and run your vehicle while checking the operation of your O2 sensors. Then check the specifications and compare. If bad, best is to replace bad sensor. If you go online, you may find more affordable parts.

SOURCE: check engine light on...

Karen,

This sounds to me like it may be the Mass Air Flow Sensor is bad. There really is no actual way to test this sensor. I would recommend either another scan from a different parts store or possibly replacing the Mass Air Flow Sensor. Hope this helps.

SOURCE: Engine light came on - yellow. Code: P0134 02

there is either a problem with the wiring going to the front oxygen sensor, or with the oxygen sensor itself. good luck!

Instrument panel on 2003 Honda CRV starts flashing when headlights are on


Have had a similar experience with my 2000 Ford Windstar. The extra load added by turning on the headlights affects the instrumentation power feed. The illumination flickers and the gages go crazy. Your 2003 CRV may have its original battery which is near death. It took me four batteries to stabilize things and I still get the flickers at night sometimes

My malfunction indicator light has been on for the past couple of weeks. I just replaced all the spark plugs and coils about 6 months ago because my light was coming on then. I took it to my local autozone...


Bear in mind that the guys at autozone were delivering news papers two weeks ago and the generic analyzer they use costs less than $45.00. It is a 2004 Honda, you can spend a buck on it. Take it to a real shop with real mechanics and have them put a real analyzer on it.
