P0134 P0135 Honda CRV

Fix code P0134 P0135 Honda CRV

Honda has discovered a recurring problem in 2007-09 Honda CRV that can result in P0134, P0135, P0171, P1157 trouble codes. Honda has traced the problem to excess grease in the underhood fuse box that melts under high heat conditions and wicks down to the oxygen sensor connector, shorting out the sensor. Honda has designed a sub-harness (06322-SWA-305, H/C 9050097) that you install between the existing connector and the replacement sensor. Install the sub-harness in an upward loop to stop the grease from entering the sensor connector. For more information consult service bulletin 08-067 dated Jul, ‘09

And you need access to the latest technical service bulletins so you don’t waste time and money replacing parts that may misbehave due to a manufacturer’s software glitch. Forget about those cheap manuals you find at the auto parts store. They will just lead you astray. Here are the two best online shop manuals around.
