Pending code? The user manual for your device says it should say "PD" for pending codes, so maybe not. "P0130 P" isn't a valid DTC for your vehicle so pending code is really all that makes sense. More specific to your model P0130 is front oxygen sensor circuit range/performance problem (Lean) Possible causes: Open wire to O2 Sensor Short to ground in O2 ...
Buy the correct O2 sensor, hacking up the OEM harness to put a different O2 sensor on the car is a bad idea.
Looking at the description of the California O2 sensor for your car, the only thing different on it (besides the internals) is the electrical plug. The wrench which you tighten it down with is 7/8", which means the sensor bung should be the same size as well. I don't think there is any real external difference between the California and non-California ...
check the part number on the new sensor. The shorter connector pigtail and new 02 sensor circuit codes appearing after the repair sound strange to me. Couldn't hurt to double check at least
The 50 g/s max flow reading that you are getting is far lower than what merely altitude can explain. The chart above shows that at about 5,200 ft above sea level, the density of air is 83% of what it is at sea level (0.062 lb/cu.ft vs. .075 lb/cu.ft). So to account for the altitude, you should multiply your expected mass flow by 0.83. According to the ...
The fault code P0171 descriptor is Bank 1 running weak. The fault code P0174 descriptor is Bank 2 running weak. This means that your engine has too much air or not enough fuel for proper ignition. This can be a faulty MAF sensor as it is common to both banks. It can also mean that you have an air leak between the MAF sensor and the throttle body, a faulty ...
I have a 1st Generation (1995-1999) Toyota Avalon with a P1135 error also. I change the Denso Air Fuel Sensor P/N: 234-9007 and it solve the problem and the check engine light went away. I change it from the top instead of going under the car it was really easy. Hope this help like other have help me.
I got the same code with 2000 tundra. I found you need to compare HO₂S Sensor 2 to engine load. If engine load is low enough, the sensor voltage should be 0 for a period of time as well. When decelerating, engine load is low, rpm is low and throttle position probably is close. Not a technician, just leaning.
