Where does the power come from on a Honda CRV?
In a nutshell, when you turn the key to crank and start your 1997-1998 2.0L Honda CR-V: 12 Volts flow into the distributor across the black with yellow stripe ( BLK/YEL) wire of the engine wiring harness distributor connector. These 12 Volts feed power to the igniter (ignition control module) and the ignition coil.
How do you test the spark plugs on a Honda CRV?
Connect the spark tester to the wire. Ground the tester to a good metal location on the engine. Crank the CR-V’s engine. Look for a spark at the tester. A blue spark is strong, while orange or yellow means weak. Repeat this test for all the spark plug wires. Perform the coil test if all the wires show weak sparks or nothing.
Where does fuel injection signal come from on Honda CRV?
The distributor shaft starts to turn (as the engine cranks and starts) which gets the CKP, TDC, and CYL sensors to produce their signals. These signals are fed directly to your Honda CR-V’s fuel injection computer.
Where is the ignition coil located on a Honda CRV?
This ignition system wiring diagram applies to the 1997 and 1998 2.0L Honda CR-V. The ignition coil, the ignition control module (igniter), the CKP sensor, the CYL sensor, and the TDC sensor are located inside the distributor.
