Timing Control Systems

NOTE: Ensure increasing engine speed advances ignition timing.

Ensure transmission is in Neutral or Park and parking brake is set. Inspect crankshaft pulley timing mark and timing mark indicator on timing belt cover. Clean marks as required. Start engine and warm to normal operating temperature. Turn all accessories off. Attach timing light to No. 1 spark plug wire. Ensure idle speed is correct. See IDLE SPEED SPECIFICATIONS table in the SPECIFICATIONS - 1.3L DOHC article in this section.
CAUTION: Driving with jumper wire installed in monitor connector will damage catalytic converter.
Connect ground terminal "D" and test switch terminal "E" of monitor connector. Aim timing light at crankshaft pulley and timing cover timing marks. If ignition timing is not within specification, loosen distributor hold-down bolt and rotate distributor to obtain correct ignition timing. See IGNITION TIMING table in the SPECIFICATIONS - 1.3L DOHC article in this section. Tighten distributor hold-down bolt, and recheck ignition timing.

NOTE: With jumper wire installed, timing should be fixed. If timing varies, terminal "D" is not properly grounded.
