Every time I get the bad sensor message and head to the dealer, its turn off before I get there. Very fustrating. Mine comes on 1-3 times per week, and will stay on for 10-15 minutes before going away. Everything is stock.
ok that is bunk and this is why, any time any code is set period there will be binary to follow. what i mean is when any light is set it will set a code.and it will store a code.so there will be a sensor fault in the pid monitor area of the ids. if the tech was informed with good training he would now this. tell them next time you take it to look at pid monitor data and all the faults will be in there. trust me.
just to back up what i say here it is right from the manual
TPMS Last Warning Event PID Definitions
The TPMS uses the TPMS last warning event PIDs to store detailed information about the last 5 times the TPMS warning indicator was activated. These PIDs can be used to acquire more information about a particular TPMS event.
EVT1_IGN through EVT5_IGN
The number of key cycles since the TPMS warning indicator was activated. This PID cycles from zero to 255 and then starts over from zero again. This can be used to determine how long ago a TPMS event occurred and the time (in key cycles) between events.
EVT1_TLOC through EVT5_TLOC
This is the last programmed location for the sensor identifier causing each TPMS event. Due to tire rotation, the sensor may no longer be at the original location. It is suggested that all the PIDs be recorded, the system retrained, and then the sensor identifier PIDs be used to pinpoint the actual location of each sensor.
EVT1_PSI through EVT5_PSI
This is the tire pressure associated with each TPMS warning indicator event. This can be used along with the function code to clearly identify the TPMS events that were strictly due to low pressure. It can also be used to determine when a sensor is transmitting inaccurate tire pressure.
EVT1_STAT through EVT5_STAT
Describes the warning status of each TPMS event by using the information received from the TPMS status (TP_STAT) PID. If there is a communication issue, the status could be Normal.
so go back and make them fix it correctly im glad i dont work there i would be pissed off.
also if they rotated your tires i hope they reset the monitors cause that will set light too if they didnt adjust presures. i hope this helps.
