Its on left side of engine, just ahead of the cat converter on that side. sensor #1 on each side are always before the cat converters, #2 sensors are after cat converters.
requires either 7/8 wrench or 22mm wrench or o2 sensor socket to remove
SYMPTOM P0133-1/1 02 SENSOR SLOW RESPONSE WHEN MONITORED With ECT greater than 147 °F , after reaching a vehicle speed of 10 mph , and the throttle remaining open (off idle) for 2 minutes , bring the vehicle to a stop and allow the engine to idle with the transmission in DRIVE. SET CONDITION The oxygen sensor signal voltage is switching from below 0.27 of a volt to above 0.62 of a volt and back fewer times than required.
Is that accessible by removing the left front tire or do I have to remove it from underneath?
serviced from underneath
WARNING: THE EXHAUST MANIFOLD, EXHAUST PIPES AND CATALYTIC CONVERTER BECOME VERY HOT DURING ENGINE OPERATION. ALLOW ENGINE TO COOL BEFORE REMOVING OXYGEN SENSOR.
CAUTION: When disconnecting sensor electrical connector, do not pull directly on wire going into sensor.
INSTALLATION Threads of new oxygen sensors are factory coated with anti-seize compound to aid in removal. DO NOT add any additional anti-seize compound to threads of a new oxygen sensor.
Also, This car is being driven on very short trips daily. 2-3 miles once or twice a day. could that be a factor? could it be a cause of failure? Would some freeway travel time clean it out?
how many miles on it now
close but o2 sensors begin acting up closer to 90k -100k in most cases. some fail earlier. very possible you had intermittant and the code is now set. cant say whether a good hard drive and blowout will do it but.. you brief drives do not allow time for the sensor heaters to fully warm that help clean them so.. yes, very possible a few good drives will clean. This code will not leave you stranded. may drop gas mileage slightly is about all
