Many malfunctions in the electrical system are caused by poor harness(s) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
Check the following conditions:
Check for damaged harness and terminals: contact resistance, oxidation, bent or broken terminals.
Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection
Use a suitable male pin to ensure that contact in sockets is good. The pin should remain in position when pulled gently.
Has a problem been found?
YES
Repair as necessary and go to "Verification of Vehicle Repair" procedure
NO
System OK. Go to "Verification of Vehicle Repair" procedure
Turn ignition switch to OFF and disconnect ignition coil connector.
With ignition switch to ON
Measure voltage of ignition coil battery voltage between ignition coil harnece connector and Chassis ground.
Probe(+) : Ignition coil #1.2 harness connector NO1.
Probe(-) : Chassis ground.
Specification: Approximately B+
Is the voltage within specification?
YES
Go to "CIRCUIT INSPECTION FOR CKPS"
NO
Open or Short circuit to chassis ground between ignition coil harness connector and ignition switch harness connector
Repair as necessary and go to "Verification of Vehicle Repair"
1.In case,when ignition connector is disconnected,the voltage at terminal 1 is 0V.
▶Possible cause : Open or short circuit of battery line between FUSE 18(15A) of I/P-J/BOX and terminal 1 of ignition coil.
Start engine.
Probe(+) : Check wave form at terminal 2 of CKPS
Probe(-) : Chassis ground.
Is the wave form displayed normally?
YES
Go to "Component Inspection"
NO
Go to "P0335 Crankshaft position sensor - no signal"
Repair as necessary and go to "Verification of Vehicle Repair"
