This section has been included to assist with the identificationof Tridon’s extensive range of engine oil pressure senders andsensors. Photographs and specification tables are shown foreach Tridon part number. Each specification table containsspanner size, thread size, plug type, circuit diagram andpressure rating.The Tridon oil pressure senders and sensors range has beendeveloped to operate within original equipment manufacturer’sspecifications. As oil pressure values vary always refer to thevehicle application list to ensure correct part number selection.Oil Pressure Senders And Sensors

Oil PressureSenders andSensorsFunctionThe engine oil pressure sender/sensor is used to measure the integrity ofthe engine lubrication system. Normally located in the engine block, theoil pressure sender responds to changes in engine oil pressure modifyingthe signal from oil pressure instrumentation. This modified signal is used todetermine the engine oil pressure via oil pressure light or gauge.There are 3 main types of engine oil pressure senders and sensors;spring controlled diaphragm, thermal transducer and piezo-resistor.Spring Controlled Diaphragm Contains a spring loaded diaphragm designed to open a set ofcontacts as pressure increases.For operation of oil pressure lights (only ON or OFF switch position).Thermal Transducer Contains a diaphragm designed to close a set of contacts attached to abimetal alloy leaf. The bimetal leaf deflects with changes in oil pressure.A corresponding bimetal leaf in the oil pressure gauge performs thesame operation, registering the appropriate pressure reading.For operation of oil pressure gauges.Piezo-Resistor Contains a semiconductor crystal, with special resistanceproperties. Changes in these properties occur when pressure isapplied; the changes are then processed to operate an oil display.For operation of electronic oil pressure gauges.Testing and ReplacementThe engine oil pressure sender/sensor is an integral component in a vehicleengine warning system; a faulty engine oil pressure sender/sensor mayprovide incorrect warning signals leading to potential engine damage.Engine oil pressure senders/sensors should be inspected regularly, thesender/sensor should be checked for any visible signs of contaminant.Note the engine oil itself, particularly old oil or incorrect oil levels may causea sender/sensor to malfunction.When an engine oil pressure sender/sensor malfunction or fault issuspected, the engine oil pressure sender/sensor should be checked andreplaced by a trained professional.Oil Pressure Sender/Sensor Testing Procedure1. Check the oil pressure sender/sensor for visible faults or oil leaks.2. Check correct oil pressure sender/sensor operation;68

Spring Controlled Diaphragm (oil pressure lights)Measure continuity across the oil pressure sender/sensor contacts; Using an Ohmmeter, remove the terminal or plug, connect theOhmmeter between the sender/sensor terminal and the vehicleearth (ground). With the engine OFF, the reading given should be zero (0) or show aclosed circuit. Start the engine, as the oil pressure rises the reading given shouldbecome infinite or open circuit.Thermal Transducer (oil pressure gauges)Test the operation of the oil pressure gauge circuit; Remove the wiring plug or terminal, connect a potentiometer betweenterminal and vehicle earth (ground). With the ignition turned on, test the operation of the oil gauge startingthe potentiometer at a high resistance (around 500Ω) then slowlyreduce the resistance to 0Ω. The gauge should operate from lowpressure to high or a maximum pressure. (Resistance valueswill vary between make and models, test procedure should beused as a guide only).Piezo-Resistor (electronic oil pressure displays)For testing procedures for a Piezo-resistor type sensor refer toThermal transducer type tests.3. Replace the sender/sensor if readings are not as shown above.4. Other oil pressure circuit tests include; Gauge and light tests with a potentiometer.Wiring tests, open and short circuits.Available voltage (check fuses) - voltage stabilizer or voltageregulator normally located in the instrument cluster.The Tridon engine oil pressure sender/sensor range has been developedto operate with OEM specifications.

As Tridon water temperature sender circuits varyalways refer to the Tridon vehicle application list to ensurecorrect part number selection.Water Temperature Senders

FunctionThe water temperature sender is used to measure the integrity of the enginecooling system. Located on the engine side of the thermostat in the coolingsystem, the water temperature sender responds to changes in enginecoolant temperature modifying the signal from engine temperatureinstrumentation. This modified signal is used to determine the enginecoolant temperature via water temperature light or gauge.The most common type of water temperature sender is a thermistor typesender unit, containing semiconductor materials which respond to coolanttemperature changes. Most commonly used are thermistors with a negativetemperature coefficient (NTC), which respond with decreasing resistanceas the temperature increases. This decrease in resistance creates a highercurrent flow through the bimetal leaf located inside the temperature gauge,indicating the appropriate engine temperature reading.Testing and ReplacementThe water temperature sender is an integral component in a vehicleengine warning system; a faulty water temperature sender may provideincorrect warning signals leading to possible engine overheating andpotential engine damage.Water temperature senders should be inspected at regular serviceintervals, the sender should be checked for any visible signs ofcontaminant and conductivity. Note the coolant itself, particularlyold coolant, incorrect coolant levels or mixture may cause the senderto malfunction.When a water temperature sender malfunction or fault is suspected, thesender should be checked and replaced by a trained professional.77

WaterTemperatureSendersWater Temperature Sender Testing Procedures1.Remove the water temperature sender from the vehicle.2.Check the water temperature sender for visible contaminant,conductivity or leaks.3.Check correct water temperature sender operation;Suspend the sender in a beaker filled with water so that thebulb is covered.Using an Ohmmeter, measure the resistance across theterminals (or terminal to the body of the sender).Heat the water until a simulated engine operating temperature isachieved (80 C - 90 C). The sender is designed to respond to thechange in temperature (as the water temperature increases thesender resistance will decrease or has a negative temperaturecoefficient NTC).At low temperatures the resistance values may be several thousandohms (Ω) and reduce to as low as a few hundred ohms (Ω) at normalengine operating temperatures. 4. Other water temperature circuit tests include;Gauge and light tests with a potentiometer.Wiring tests, open and short circuits.Available voltage (check fuses) - voltage stabilizer or voltage regulator,normally located in the instrument cluster.The Tridon engine water temperature sender range has been developedto operate with OEM specifications.

FunctionThe coolant temperature sensor is a device designed to respond tochanges in coolant temperature, this response causes a change in signalvoltage which is returned to the vehicle computer (ECU). The registeredchange in voltage signal is then processed by the ECU to determine theengine temperature. The coolant temperature sensor is crucial for thecontrol of temperature based functions performed ECU (e.g. ignition,instrumentation, fuel metering and transmission shifting).There are two types of coolant temperature sensors, the thermocoupletype and more commonly used thermistor type, normally located in thewater jacket of the engine cylinder head or intake manifold. The thermistortype contains conductive materials which respond to coolant temperaturechanges. Two types of conductive material are used; material with apositive temperature coefficient (PTC), where the resistance increases asthe temperature increases. Alternatively and more commonly used ismaterial with a negative temperature coefficient (NTC), which respondswith decreasing resistance as the temperature increases.The coolant temperature sensor is critical to many temperature basedfunctions performed by the ECU, these include; Electronic fuel injection system.- Changes to injector pulse width.- Operation idle speed solenoid. Ignition Timing systems.- Changes to

a sender/sensor to malfunction. When an engine oil pressure sender/sensor malfunction or fault is suspected, the engine oil pressure sender/sensor should be checked and replaced by a trained professional. Oil Pressure Sender/Sensor Testing Procedure 1. Check the oil pressure sender/sensor for visible faults or oil leaks. 2.
