Questions & Answers
I have these errors my OBDII scanner P0152, P0194 and P0303 on does anyone know what the issue could be or how to fix this?
P0152 is the first oxygen sensor on bank 2 high voltage/////P0194 is your fuel rail sensor circuit is intermittent meaning it is and isn't working check the wiring harness going to it or the plug that goes into it for shorting out burnt looking and also the fuse for it////P0303 is your #3 cylinder misfire detected which you know already changing the plug was good but did you find moisture in the plug chamber?or did you roll the plug boot in your fingers to check for cracks in it or if it was very soft?any of these things will cause that code to set because the +voltage is leaking to -ground but that fuel rail sensor could also be causing that it works then it don't? Also the 02 sensor is a problem here because your computer is trying to adjust for the conditions so you know this bank 2 is at the front your engine is sideways front wheel drive bank 1 is at the firewall windshield side fix the 152 and 194 then see if the 303 clears itself otherwise there's a problem maybe your injector for #3 is clogged did you get gas from somewhere different then usual my be a dirty fill up or water in the gas put 2 cans of fuel injection cleaner in and also clean out your throttle body dirty injectors will cause a misfire but not show a code for that injector because it's still working it's just not letting the right amount of fuel through so the air fuel mixture is not correct I would start here first then do the rest listed above good luck stephen

Where are the fuses in a 2007 toyota corolla
Quite possibly a fuse or relay for the interior cabin fan (heat and cool) has failed. Search for "location of fuses for 2007 corolla" to find out where they're located, and to find a diagram. Once you've identified the fuse/relay, try replacing it. If the fan has failed, though, it might blow out again and you'll have to replace the fan motor (which is usually a TRULY pita job). Before doing that, however, make sure that the rest of the A/C system (compressor, electric radiator fans, etc.) is working properly.

What is the code for a bad gas cap? I just
codes p 0440 through to p 0459 all refer to the EVAP system.
code p 0455 refers to EVAP system very large leak which refers to a loose or missing gas cap
manifold leaks are a small leak in the codes and many are miss- read as a vacuum leak can be from the transmission actuator hose missing , and the vent controls leaking
A lot of the EVAP codes refer to the purge valve or the purge valve solenoid
