CLEARING FAILURE CODES
Notice:To prevent Engine Control Module (ECM) damage, the key must be OFF when disconnecting or reconnecting
the power to the ECM (for example battery cable, ECM pigtail connector, ECM fuse, jumper cables, etc.)
Parameters listed in the table may not be exactly the same as your reading due to the type of instrument or other
factors. If a failure code is displayed during the “TROUBLE CODE” in scan tool check mode, check the circuit for the
code listed in the table below. For details of each code, turn to the page referred to under the “See Page” for the re-
spective “Failure Code” in the below table.
Failure codes should be cleared after repairs have been completed.

IGNITION SYSTEM
This ignition system does not use a conventional distributor andcoil. It uses a crankshaft position sensor input to the
Engine Control Module (ECM). The ECM then determines Electronic Spark Timing (EST) and triggers the electronic
ignition system ignition coil.
This type of distributorless ignition system uses a‘‘waste spark” method of spark distribution. Each cylinder is paired
with the cylinder that is opposite it (2 -- 3 or 1 -- 4). The spark occurs simultaneously in the cylinder coming up on the
compression stroke and in the cylinder coming up on the exhaust stroke. The cylinder on the exhaust stroke requires
very little of the available energy to fire the spark plug. The remaining energy is available to the spark plug in the cylin-
der on the compression stroke.
These systems use the EST signal from the ECM to control the EST. The ECM uses the following information:
DEngine load (mass air flow sensor).
DEngine temperature.
DIntake air temperature.
DCrankshaft position.
DEngine speed (rpm).

IGNITION COIL
YAA1F920
The Electronic Ignition (EI) system ignition coil is located on the cylinder head cover. The double ended coils receive
the signal for the Engine Control Module (ECM) which controls the spark advance.
Each EI system ignition coil provides the high voltage to two spark plugs simultaneously;
T1/1: cylinder 1 and 4
T1/2: cylinder 2 and 3
The EI system ignition coil is not serviceable and must be replaced as an assembly.

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.
