READ VALUE USING TECHSTREAM (ENGINE SPEED)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(e) While running the engine, read the [Engine Speed] value.
Standard:
A value that matches the actual engine speed is constantly output.
HINT:
Check the engine speed using a line graph.
If the engine cannot be started, check the engine speed while cranking the engine.
If the engine speed is 0 rpm, the crankshaft position sensor may have an open or short circuit.
