DInspection the ECM
Circuit Description
The Electronic Ignition (EI) system uses a waste spark method of spark distribution. The Crankshaft Position (CKP)
sensor sends reference pulses to the ECM. The ECM then triggers the EI system ignition coils. Once the ECM triggers
the EI system ignition coils both of the connected spark plugs fire at the same time. One cylinder is on its compression
stroke at the same time that the other is on the exhaust stroke, resulting in lower energy needed to fire the spark plug in
the cylinder on its exhaust stroke.
This leaves the remainder of the high voltage to be used to fire the spark plug in the cylinder on its compression stroke.
Since the CKP sensor is in a fixed position, timing adjustments are not possible or needed.

Circuit Description
The 58X reference signal is produced by the CKP sensor. During one crankshaft revolution, 58 crankshaft pulseswill
be produced. The ECM uses the 58X reference signal to calculate engine rpm and CKP. The ECM constantly monitors
the number of pulses on the 58X reference circuit and compares them to the number of Camshaft Position (CMP)
signal pulses being received. If the ECM receives and incorrect number of pulses on the 58X reference circuit, this
failure code will set.
Crankshaft Position Sensor Resistance Inspection
1. Disconnect the coupling “E” of ECM while the ignition switch is in “OFF” position.
2. Measure the resistance between the coupling terminal pin No. 99 and No. 100 using a multimeter.
Specified Value
1,050 ~ 1,400Ω
Notice:Measure the insulator resistance of the CKP sensor if out of the specified value.

Circuit Description
The CMP sensor sends a cam position signal to the ECM. If the cam position signal is lost while the engine is running,
the fuel injection system shifts to a calculated sequential fuel injection mode based on the last fuel injection pulse, and
the engine continuous to run.
Camshaft Position Sensor Signal Voltage Inspection
1. Measure the voltage between the ECM terminal No. 11 and No. 106 while the engine speed is at idle.
Specified Value
1.2~1.7v
Notice:The signal voltagewill be changed in the range of 1.2 ~ 1.7 v.

Circuit Description
The KS system is used to detect engine detonation, allowing the ECM to retard the ignition control spark timing based
on the KS signal being received. The KS signal’s amplitude and frequency depend upon the amount of knock being
experienced. The ECM monitors the KS signal and can diagnose the KS sensor and circuitry.
Knock Sensor Resistance Inspection
1. Disconnect the coupling from ECM while the ignition switch is in “OFF” position.
2. Measure the resistance between the coupling terminal pin No. 118 and No. 117 and terminal pin No. 115 and No.

Notice:Replace the KS if the measured values is out of the specified values. Check the connector and wire connec-
tion between ECM and the KS if the measured values are normal.

Circuit Description
The ECM monitors the crankshaft and camshaft positions to detect if the engine is misfiring. The ECM looks for a quick
drop in crankshaft speed. Misfire multiple cylinder is monitored by engine roughness measuring. The actual roughness
value is compared with the actual (emission and catalyst damage) threshold.
