Exam 6: Tire Pressure Monitoring Systems

Technician A says a loose tie rod end is ok when aligning a car. Technician B says that recalibrating the steering angle sensor is needed on most recent vehicles. Who is correct?

TPMS sensors can be mounted by which of the following methods?

The air pressure on a vehicle with TPMS is supposed to be 35 psi. Technician A says that one some vehicles, a 5 psi drop below 35 psi will cause the TPMS light to illuminate. Technician B says that on other vehicles, a 2 psi will cause the light to illuminate. Who is correct?

The __________ measures the air pressure in a tire by monitoring wheel speeds.

The pressure sensors:

Two technicians are describing the operation of the TPMS. Tech A says that the TPMS is a mechanical system used to monitor the air pressure inside a pneumatic tire. Tech B says that the TPMS is also referred to as remote tire pressure monitoring systems (RTPMS) or simply as run-flat Indicators. Who is right?

If the TPMS warning light indicates a system fault, connect an appropriate scan tool to the system and read any ________.

Vehicles that are 2008 model year and newer are required to be equipped with a ________, designed to monitor the pressures in each individual tire and alert the driver of a problem if a tire pressure is outside of the specified limits.

Technician A says that dismounting and mounting a tire is the same process on all modern wheels. Technician B says that the tire pressure monitoring system has changed mounting and dismounting procedures on some vehicles equipped with TPMS. Who is correct?

A TPMS 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) required by doing which of these?

Tech A says that the use of nitrogen to fill a tire will prevent the tire from blowing out. Tech B says that when mounting or dismounting a tire on a wheel with a TPMS sensor, you need to position the wheel/tire properly on the tire machine or the TPMS sensor can be easily broken. Who is correct?

The use of a(n) ________ in the sensor allows the sensor to go to sleep when the vehicle stops, which extends battery life.

The mode of sensor operation where a very fast change in inflation pressure is detected and inflation pressure is sent to the control module approximately once a second is:

How is the indirect TPMS system reset?

The steering column of a vehicle with EPS or stability control will be equipped with a _______.

A special tool that is used to reset the sensors when rotating the tires is the:

Tech A says that a TPMS system can save fuel over time. Tech B says that a TPMS will help prevent blowouts. Who is correct?

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

Technician A says that you do not need to be concerned about damaging a TPMS sensor if servicing a tire/wheel assembly. Technician B says that some sensors are attached to the valve stem while others are clamped into position in the wheels drop center. Who is correct?

All of the following statements about a tire pressure monitoring system are true, EXCEPT:
