Exam 6: Tire Pressure Monitoring Systems

The TPMS sensor that sends a signal to the receiver when exposed to a powerful electromagnetic force is the:

Where do you find the most accurate tire pressure specifications for TPMS operation?

Many TPMS sensors use ________-plated valve cores in an aluminum valve stem.

TPMS sensor batteries are designed to last for _______ years without replacement.

The National Highway Traffic Safety Administration requires the TPMS to notify the driver when any tire is:

The valve stem-mounted sensor uses the valve stem as which of these?

All of the following statements about a TPMS system are true, EXCEPT:

The sensors in the ________ provide information to a steering control module for electric power steering assist or for the electronic stability control system.

Technician A says that TPMS sensors that are fastened to the inner end of the valve stem are called direct sensors. Technician B says an indirect TPMS system does not use pressure sensors. Who is correct?

Which piece of U.S. legislation is responsible for the TPMS?

The ________ monitors the tires for low air pressure and alerts the driver when one or more tires are lower than (or in some cases, higher than) the designated thresholds.

There are two basic configurations used to monitor the vehicle's tire pressures: ________ and ________.

Technician A says that underinflated tires reduce fuel economy. Technician B says that underinflated tires are unsafe and cause accelerated tire wear. Who is correct?

All vehicles must comply with the TREAD Act, except:

Technician A says some tire pressure monitoring systems have a sensor mounted in each wheel rim. Technician B says some tire pressure monitoring systems use the wheel speed sensors in the ABS system to detect tire pressure. Who is correct?

Many TPMS valve stems have valve cores with ________ threads and should not be replaced with ________ threads.

Tech A says the direct TPMS measures tire pressure, sometimes via a sensor that is installed inside each wheel. Tech B says the indirect TPMS measures the air pressure indirectly by monitoring individual wheel speeds and other signals available in the vehicle using the ABS (antilock brake system) wheel speed sensors. Who is right?

Technician A says that there are two different types of direct tire pressure monitor sensors. Technician B says that some direct tire pressure sensors can receive and send signals to the TPMS control unit. Who is correct?

________ valve stems may be made as part of the valve stem or may screw onto, or snap into, the valve stem, which is replaceable.

Tech A says that the banded sensor is installed in the drop well of the wheel inside the tire and banded or clamped around the drop well of the wheel. Tech B says that the TPMS pressure sensor uses a lithium-ion battery. Who is right?
