I bought my 2005 CRV last april and I love it. I should note that when I got my car stereo installed the dude found a mouse nest behind the old radio. Car fax report showed it must have been parked (probably in a barn) for 3 years. The wires behind the radio looked fine but I was worried about potential electrical problems after that. Here's the thing, I average about 25mpg ish, which ive heard about people getting upwards of 30 and naturally with the O2 sensor malfunctioning Im hoping i can get better MPG and simply not have all these codes popping up. The weird thing is although all these codes have popped up(some time after buying the car too, not right away), the car hasnt had any noticable operating issues that might be associated with a failed O2 sensor except the possible less than ideal MPG.
The low down on most recent scan:
P0141 bank 1 sensor 2 heater circuit malfunction(this is the one i replaced) for some reason this code showed up twice on the print out
P2422 EVAP CVS stuck closed. This code also showed up twice on the print out
P1078 IMT (IMRC) Valve stuck
I checked the fuse for the O2 sensor and cant seem to find any wiring problems that are evident.
I haven't gotta around to check the connections to the ECM yet as it got late but will do that tomorrow.
Haven't checked the evap unit yet either and will also do that tomorrow.
Here's the gist of what im starting to think is the culprit. Is it possible that the ECM is failing? I found it strange that I had one code, and then almost immediately these other codes. And again replacing the O2 sensor did not resolve the code. After doing a voltage test on the o2 sensor connector with the car "on but not running" it appears there is basically no power being sent to the O2 sensor. I appreciate any incite into this , I haven't even had this car a year and i really dont want all this shit to lead to more problems or damage.
