Subaru released this TSB to explain the inspection, diagnosis and replacement procedures for the washer fluid level sensor. Applicable vehicles include the 2006 and later Tribeca, 2010 and later Legacy and Outback and 2012 Impreza.
Some 2011 Mazda2 vehicles may experience MIL illumination with DTC P0451:00 (fuel tank pressure sensor range/performance problem) stored in PCM memory. This may be caused by water or snow entering and freezing in the atmosphere breather hose in the FTP (fuel tank pressure sensor).
According to Hyundai, incorrect operation of the oil temperature sensor (automatic transaxle) may result in the check engine light illuminated and DTCs P0711, P0712 or P0713.
Some 2009-2011 Ford Taurus, Edge and Flex, and 2009-2011 Lincoln MKS, MKT and MKX vehicles built from 3-13-2009 to 6-30-2010 and equipped with the 6F50 or 6F55 transmission may intermittently exhibit slipping/neutral out, 5th gear start from stop, electronic PRNDL error, backup camera-on in Drive or speed control dropping out. This may be caused by high resistance in the transmission range (TR) sensor.
Some Mazda vehicles (2007-2009 Mazda3 and 2007-2010 Mazda5 produced before Nov. 6, 2009), may experience the MIL on with DTC P0131/P2251 because the A/F sensor connector bracket contacts and damages the sensor harness. To prevent interference, the shape of the sensor connector bracket has been changed
Some technicians who have worked in this business for years often still get confused by how to diagnose an air-fuel sensor or are not sure what to look at when diagnosing a rear oxygen sensor. In fact, when I started in this business (which is not that long ago) I was told that there is no way to diagnose an air-fuel sensor with a high level of certainty. Let me set the record straight: there are several ways that you can diagnose any air-fuel or oxygen sensor and be confident that you will be doing the right repair.
The Bosch Group advises motorists to check and or replace a “lazy”oxygen sensor with every tune-up to improve vehicle performance, reduce harmful exhaust emissions, save on fuel cost and prevent premature failure of the catalytic converter.
