5-20 6.1 COMPONENT TESTS Preset Operation The instrument provides predefined setups for a variety of vehicle sensors and circuits. To choose a preset test, select COMPONENT TESTS from the MAIN MENU. From the resulting menu, select a test group: • SENSORS • ACTUATORS • ELECTRICAL • IGNITION Then select a specific test from those listed.
• Troubleshooting Tips If the amplitude is low, look for an excessive air gap between the trigger wheel and the pickup. If the amplitude wavers, look for a bent axle. If one of the oscillations looks distorted, look for a bent or damaged tooth on the trigger wheel.
• Symptoms [OBD II DTC’s : P0420 ~ P0424, P0430 ~ P0434] Emissions test failure, poor fuel economy. • Test Procedure 1. Connect one shielded test lead to the CH A and the other test lead to the CH B.
4. Press the HOLD key to freeze the waveform on the display for closer inspection. 5. To measure resistance, disconnect the sensor before changing to the GMM mode and then connect the Ground and CH A leads to the terminals on the sensor. • Reference Waveform VEHICLE INFORMATION YEAR : 1986 MAKE : Oldsmobile MODEL : Toronado ENGINE : 3.
• Symptoms [OBD II DTC’s: P0110 ~ P0114] Poor fuel economy, hard start, high emissions, tip-in hesitation • Test Procedure 1. Backprobe the terminals on the IAT sensor with the CH A lead and its ground lead.
Throttle Position Sensor (TPS) • Theory of Operation A TPS is a variable resistor that tells the PCM the position of the throttle, that is, how far the throttle is open, whether it is opening or closing and how fast.

Analog Manifold Absolute Pressure (MAP) Sensor • Theory of Operation Almost all domestic and import MAP sensors are analog types in design except Ford’s MAP sensor. Analog MAP sensors generate a variable voltage output signal that is directly proportional to the intake manifold vacuum, which is used by the PCM to determine the engine load.
3. Make sure that the amplitude, frequency and shape are all present, repeatable, and consistent. Amplitude should be close to 5 V. Frequency should vary with vacuum.
• Troubleshooting Tips If overall voltage is low, be sure to check for cracked, broken, loose, or otherwise leaking intake air ducts. IMPORTANT: 0.25 V can make the difference between a good sensor and a bad one, or an engine that is blowing black smoke and one that is in perfect control of fuel mixture.
4. Make sure that the sensor generates the correct frequency for a given RPM or airflow rate. 5. Use the Glitch Snare mode to detect dropouts or unstable output frequency. • Reference Waveform VEHICLE INFORMATIONS YEAR : 1990 MAKE : Buick MODEL : Le Sabre ENGINE : 3.

Saturated Switch Type (MFI/PFI/SFI) Injector • Theory of Operation The fuel injector itself determines the height of the release spike. The injector driver (switching transistor) determines most of the waveform features. Generally an injector driver is located in the PCM that turns the injector on and off.
• Test Procedure 1. Connect the CH A lead to the injector control signal from the PCM and its ground lead to the injector GND. 2.

How much and when EGR flow occurs is very important to emissions and driveability. To precise control EGR flow, the PCM sends Pulse Width Modulated signals to a vacuum solenoid valve to control vacuum flow to the EGR valve. When applying vacuum, the EGR valve opens, allowing EGR flow.
IMPORTANT : Before diagnosing IAC motor, several things must be checked and verified; the throttle plate should be free of carbon buildup and should open and close freely, the minimum air rate (minimu.

3. Exercise the sensor, device, or circuit while watching for the amplitude of the signal. The amplitude should stay in a predetermined voltage range for a given condition. 4. In most cases, the amplitude of the waveform should stay at the battery voltage when the circuit is on, and go to 0 V when the circuit is off.
• Test Procedure 1. Connect the CH A lead to the GND pin of the grounded device or the one side of the suspect junction and its ground lead to the chassis GND or the other side of the suspect junction. 2. Make sure power is switched on in the circuit so that the sensor, device, or circuit is operational and current is flowing through the circuit.
Alternator Field/ VR (Voltage Reference) • Theory of Operation A voltage regulator (in the PCM) controls alternator output by adjusting the amount of current flowing through the rotor field windings. To increase alternator output, the voltage regulator allows more current to flow through the rotor field windings.

Some tips to keep in mind : • Always position the piezo pickup on the fuel line at about the same distance from the injector. • Place the pickup on a straight part of the fuel line. Don’t place it on a bent part of the line. • Always compare results with a reference waveform from a good diesel engine to get acquainted with the signal shape.
