Code No. Throttle position sensor system Probable cause
[Comment] of the throttle If the TPS output becomes 4.6 or more at idle, TPS output is excessive, and of connector
trouble code No. 11 is output. If the TPS output be comes 0.2 or less at times other than l of idling, TPS output is insufficient and diagnostic t rouble code No. 12 is output. If the TPS output
and the target value inside the TCM do not match ev en after compensation is carried out while
the engine is idling, the TPS sensor is defective and diagnostic trouble code No. 13 is output.
If the TPS voltage becomes 0.2 or less or 1.2 or more while the engine is idling, the
TPS adjustment is defective and diagnostic trouble code No. 14 is output.

Code No. 15, 16 Oil temperature sensor system
[Comment] If the oil temperature sensor output is 4.4 or higher (oil temperature does not increase) evenafter driving for 10 minutes or more, there is an o pen circuit in the oil temperature sensor
and diagnostic trouble code No. 15 is output.
When the oil temperature sensor output is 0.2 or less (for 1 second or more), it is judgedthat there is a short-circuit in the oil temperatur e sensor and diagnostic trouble code No. 16is output.
