Subaru P0335 mistakenly set

This TSB refers to 2008 Subaru Impreza  models. If the ignition key is held between the ON and START position for more than three seconds, there is the possibility that P0335 can be stored in memory (crankshaft position sensor A circuit). This is caused by an erroneous signal being sent to the ECM. Under normal operation of the ignition switch, this will not occur.


Nissan cold engine idle fluctuation

This TSB applies to 2010-2011 Nissan Altima sedan and coupe models, and involves idle speed fluctuations when the engine is cold (has not reached normal operating temperature). Once operating temperature has been reached, idle speed is normal and stable.


Nissan cold start control

This TSB applies to the 2009-2010 Nissan Cube. If the MIL is on and DTC P1421 is stored in the ECM, this indicates a problem with cold start control, and the ECM requires reprogramming.


Low idle Kia calls for TPS replacement

This bulletin from Kia advises that some Sedona, Sorento, Amanti, Optima and Rondo vehicles built before 4-1-2009 may require a TPS (throttle position sensor) replacement, along with an ECM upgrade.
