A vehicle with a direct TPMS system keeps showing “Low-Left Front Tire,” but when checked, the tire is within specification. Which of the following would be the most likely cause? A broken reluctor wheel Multiple TPMS sensors have failed The tires were rotated without doing a re-learn procedure A faulty wheel speed sensor

Which of the following statements regarding the “Pre-Emission Inspection Check” Of a diesel powered vehicle that is subject to Opacity (Smoke Meter) testing is not true? The governor (if equipped), the exhaust system, and the emissions control devices must all be checked.   The exhaust system must be checked for any missing sections which would prevent collection of a valid exhaust sample.   Vehicles not meeting requirements cannot be inspected. This is not considered an inspection or rejection and no fee is to be charged.   The governor, if originally equipped, must be checked for presence, connection, and operation.
