Exam 110: Tire Pressure Monitoring Systems

What mode does a direct pressure sensor enter when the vehicle is stopped?

What does the "delta pressure method" mean?

Two technicians are discussing tire pressure and temperature. Technician A says that tire pressure will drop 1 PSI for every 10 degrees drop in temperature. Technician B says that the tire pressure will increase as the vehicle is being driven. Which technician is correct?

To ensure accuracy, a mechanical tire pressure gauge should be used with TPMS.

A valve core torque wrench is needed to service TPMS tire valves.

Two technicians are discussing the indirect tire-pressure monitoring system. Technician A says that it was used by some vehicle manufacturers on vehicles before the 2008 model year. Technician B says that it uses the speeds of the RF and LR tires and compares the rotating speeds of the LF and RR tires to detect a low tire. Which technician is correct?

A vehicle with TPMS has the tire pressure warning light on steady. The owner says that all 4 tires have the correct pressure. Technician A says that the spare tire pressure could be low. Technician B says that a sensor may be bad. Who is correct?

The two basic types of direct TPMS sensors include ________.

A tire has a recommended pressure of 32 PSI. The TPMS should light the lamp when the pressure in this tire reaches ________.

Which one of these valve stems has the TPMS sensor built in?

To activate or learn a direct pressure sensor, what does the service technician need to do?

When rotating tires on a vehicle equipped with TPMS Technician A says that the sensors will be automatically relearned after driving a few miles. Technician B says that the sensor positions should be relearned, using a scan tool, before returning the vehicle to the customer. Who is correct?

All vehicles sold in the United States must have a tire pressure monitoring system, starting with model year ________.

A tire with lower than specified inflation pressure could lead to what condition?

What type of valve core is used in stem-mounted sensors?

Technician A says that the tire pressure can be 5 PSI below specification but not turn on the TPMS warning lamp. Technician B says that vehicles with TPMS do not need to have the tire pressure checked monthly. Who is correct?

The FMVSS 138 law requires that the driver be notified if the tire inflation pressure drops how much?

Technician A says that a tire pressure monitor system that uses a valve-stem-type transmitter is the direct reading type of TPMS. Technician B says that a tire pressure monitoring system that uses a sensor inside and strapped to the wheel is an indirect reading type of TPMS. Which technician is correct?

Which tire inflation information should be checked to determine the proper tire inflation pressure?

A 2008 vehicle with TPMS has a flashing TPMS warning lamp. This means ________.
