Introduction/Context / This lesson will instruct students on the proper procedures needed to inspect , test and replace oil temperature and pressure switches and sensors, and determine necessary action. Knowledge of these techniques and the skills required to correct problems associated with this task are necessary for a student to acquire if they wish to compete for high paying, high skilled jobs in an automotive repair facility. Entry level technicians need to be able to perform this task to 100% accuracy. Incorrectly performing this task can lead to an automobile accident, safety problems, or create customer satisfaction issues.

Content/Presentation/Demonstration Outline

Inform students that the oil pressure indicator is one of the most important instruments on the vehicle. Instruct students to look up vehicle information and locate the oil sending unit. Using a shop light, have students inspect the sending unit for leaks and wiring problems.
Instruct students of the different types of oil sending units. Most modern sending units are all electrically operated. Some vehicles use a warning light were others use a gauge. Inform students as with any electrical problem start with checking power and grounds. If both power and ground exist, they should check with the service manual for testing procedures. Some manufactures use a fused jumper wire and ground the circuit. The oil temperature unit uses a thermistor that changes resistance as temperature changes. Check factory service manuals for proper procedures for testing.
Instruct the students to remove the oil sending unit and install an oil pressure tester. Have students run the engine through different loads and temperatures and record their findings and compare to the factory specifications.
Inform the students that most late model vehicles have the oil pressure and temperature sending units connected to the ECM. Have students use a scan tool and monitor the oil pressure/temperature and compare with service manual specifications.
Instruct the students that some vehicles use an oil level sensor located inside the oil pan to help the driver monitor the oil level in the engine. Have students remove the oil level sensor from the oil pan and check the condition. Students can move the float and monitor the dash lights and check for warning light operation.
Instruct students to locate the sending unit. Have student’s clean area around sending unit before sensor removal. Unplug sending unit with care as not to break connector, inform students these are weather proof connectors that keep contaminates out of the connector. Instruct the students to use a sending unit socket if possible and remove oil pressure/temperature sensor. Have students use a thread sealer and install the new unit have students torque sending unit to specifications.
Instruct students to start vehicle and monitor gauges and verify their repair


Applications/Practice

1 / Refer to content


Evaluation and feedback Prior to Testing or Lab Work

1 / Objective 1/ Formative assessment / Instructor will observe students as they practice the procedure to assure correct methods and safety practices are being followed. A checklist should be utilized to chart student progress on the task. Questioning techniques will be utilized as necessary to demonstrate student comprehension / Adaptations and/or accommodations for special needs students will be added if required.


STUDENT ASSESSMENT:(Assess student progress with performance criteria.)

1 / Objective 1/ Summative assessment / written test questions on stated objective / adaptation and / or accommodations for special needs students will be added if required.
IMPACT--Reflection/Analysis of Teaching and Learning: (How did students’ progress in relation to the state objectives? Was the instruction successful? Analyze samples of student work particularly that which is unsatisfactory, for the purpose of planning further instruction.)
REFINEMENT--Lesson Extension and Follow-up: (To be filled in as the lesson is modified during initial planning and/or during the teaching learning process.)
