Digitali mages and videos are very helpful to me.It is brilliant to say the least. It is about as good as manuals get in my view. It would be nice if Porsche and BMW made them as detailed as Toyota does.I'm a very visual learner. Digitali mages and videos are very helpful to me. Also, youtube may be your friend as well. There's a bunch of tech that people post on youtube. Some of it is some redneck nonsense but some of it is good stuff. Just filter through it and you will find the useful stuff.I've had really good luck with the FSM in combination with Youtube. Sometimes the online repair guides at Autozone.com are helpful with visualizing what you're doing too. Forum posts are great, too, lots of guys posting pictures and such.Got it off Amazon.I've had really good luck with the FSM in combination with Youtube.

Connect tachometer test probe to terminal IG data link connector 1. Check idle speed. Be sure that fuel is enough in tank. Turn ignition switch on.The G1, G2 signals inform the ECM of the standard crankshaft angle. The NE signals inform the ECM of the crankshaft angle and the engine speed. Disconnect distributor connector. Measure resistance between each terminal shown. Replace distributor.Since the width of the IGT signal is constant, the dwell angle control circuit in the igniter determines the time the control circuit starts primary current flow to the ignition coil based on the engine rpm and ignition timing one revolution ago, that is, the time the Tr turns on. Spark should be generated.Repair or replace harness or connector. Check ignition coil. Disconnect ignition coil connector. Check primary coil. Disconnect igniter connector.Check voltage between terminals THW and E2 of ECM connector. Turn ignition switch on. Sensor Circuit CIRCUIT DESCRIPTION The intake air temp.The structure of the sensor and connection to the ECM is the same as the water temp.Measure voltage between terminals THA and E2 of ECM connector.

Connect terminals TE1 and E1 of data link connec- tor 1. Connect positive probe to terminal VF1, VF2 and negative probe to terminal E1 of data link connec- tor. Repair or replace harness or connector. Check each item found to be a possible cause of problem.Measure voltage between terminal HT of ECM connec- tor and body ground.Warm up engine to normal operating temperature. Measure voltage between terminal HT of ECM connec- tor and body ground, when engine is idling and racing at 2,500 rpm. It converts the intake air readings into a voltage signal by means of a potentiometer. Intake air volume signal is used to calculate the basic injection duration and basic ignition advance angle. Measure voltage between terminals VC and E2 of ECM.It converts the intake air readings into a voltage signal by means of a potentiometer. Intake air volume signal is used to calculate the basic injection duration and basic ignition advance angle. Measure voltage between terminals VS and E2 of ECM.Check voltage between terminals VC and E2 of ECM.Turn ignition switch ON. Measure voltage between terminals VTA and E2 of ECM. Check resistance between terminals 3 and 1 of throttle position sensor. Disconnect the throttle position sensor connector. After this signal is converted into a more precise rectangular wave- form by the waveform shaping circuit inside the combination meter, it is then transmitted to the ECM. Drive the vehicle and check if the operation of the speedometer in the combination meter is normal. The No. 1 speed sensor is operating normally if the speedometer display is normal. Hint Check speedometer circuit. A rich mixture is therefore necessary in order to achieve good startability. While the engine is being cranked, the battery voltage is applied to terminal STA of the ECM. Turn ignition switch OFF. Connect terminals TE2 and E1 of data link connec- tor 2. Turn ignition switch ON. (Don’t start the engine.) Connect terminals TE1 and E1 of data link connec- tor 2. This sensor contains a piezoelectric element which generates a voltage when it becomes deformed, which oc- curs when the cylinder block vibrates due to knocking. Measure resistance between terminals KNK1, KNK2 of ECM connector and body ground.Repair or replace harness or connector. Does malfunction disappear when a good knock sensor is intalled. Check and replace ECM Reference INSPECTION USING OSCILLOSCOPE With the engine racing (4,000 rpm) measure. Repair EGR system. Check resistance of EGR gas temp. sensor. Remove EGR gas temp. sensor. Measure resistance between terminals of EGR gas temp.Air Conditioning Switch Signal The ECM uses the output from the air conditioning switch to determine whether or not the air conditioning is operating so that it can increase the idling speed of the engine if necessary. Turn ignition switch OFF. Connect terminals TE2 and E1 of data link connector.Remove air conditioning control assembly. Disconnect air conditioning control assembly con- nector. Turn ignition switch on. Measure voltage between terminal AC1 of air condition- ing control assembly connector and body ground. When it goes on the terminal PNP of the ECM is grounded to body ground via the starter relay and theft deterrent ECU, thus the terminal PNP voltage becomes O V. Crank the engine. Connect terminals TE1 and E1 of data link connec- tor 2. Continuity Check for short in all the harness and components con- nected to IGN fuse (See attached wiring diagram). Check ignition switch. Turn ignition switch on. Check EFI fuse. Apply battery voltage between terminals 1 and 3. Check continuity between terminals 2 and 4. Replace SFI main relay. Continuity Check for short in all the harness and components con- nected to EFI fuse (See attached wiring diagram). Check voltage between terminal BATT of ECM connector and body ground. They inject fuel into the cylinders based on the signals from the ECM. HINT: The correct waveform appears as shown in the illustration on the below. Repair or replace harness or connector. Measure resistance of injector. The injection volume, i,e, the length of time the injector is energized, is controlled by the ECM and the cold start injector time switch. During a cold start, when the starter turns the contacts in the cold start injector time switch close. Disconnect ECM connector. Measure voltage between terminal STJ of ECM connec- tor and body ground when ignition switch is turned to STA. Measure resistance between terminals shown below. Replace start injector time switch.Disconnect IAC valve connector.

Check circuit opening relay.Repair or replace harness or connector.Repair or replace harness or connector. Repair or replace. Remove fuel pressure control VSV. Disconnect fuel pressure control VSV connector. Measure resistance between terminals. Measure resistance between each terminal and the body.Measure voltage between terminal FPU of ECM con- nector and body ground.Turn ignition switch ON.When the engine speed is 3,900 rpm or less and the throttle valve opening angle is 60 or more, the ECM turns the VSV ON and closes the IACV. Remove IACV control VSV. Disconnect IACV control VSV connector. Measure resistance between terminals. Measure resistance between each terminal and the body.Measure voltage between terminals ISAAC of ECM connector and body ground.When these terminals are connected with the E1 terminal, diagnostic trouble codes in normal mode or test mode can be read from the Malfunction Indicator Lamp on the combination meter. Us- ing data provided by sensors which monitor various engine functions (rpm, intake air volume, eng, temper- ature, etc.), the microcomputer (ECM) triggers the spark at precisely the right instant. With a tachometer connected to the system. Connect the test probe of the tachometer to terminal IG of the DLC1.
