(e) Reconnect the injector connector.

(f) Reconnect the ECM connector.

REPAIR OR REPLACE HARNESS OR CONNECTOR

CHECK FUEL INJECTOR OF MISFIRING CYLINDER

(a) Check the injector injection (whether fuel volume is high or low, and whether injection pattern is poor).

REPLACE FUEL INJECTOR ASSEMBLY

CHECK VALVE CLEARANCE OF MISFIRING CYLINDER

ADJUST VALVE CLEARANCE

CHECK AIR INDUCTION SYSTEM

(a) Check the air induction system for vacuum leakage. OK:

No leakage from air induction system.

REPAIR OR REPLACE AIR INDUCTION SYSTEM

CHECK VALVE TIMING

(a) Remove the cylinder head cover.

(b) Turn the crankshaft pulley, and align its groove with the timing mark "0" of the timing chain cover.

(c) Check that the timing marks of the camshaft timing gears are aligned with the timing marks of the bearing cap as shown in the illustration.

If not, turn the crankshaft 1 revolution (360°) and align the marks as above.

Timing marks on camshaft timing gears are aligned as shown in illustration.

(d) Reinstall the cylinder head cover.

ADJUST VALVE TIMING

CHECK FUEL PRESSURE

(a) Check the fuel pressure (See page FU-6).

CHECK AND REPLACE FUEL PUMP, PRESSURE REGULATOR, FUEL PIPE LINE AND FILTER

READ VALUE OF INTELLIGENT TESTER (COOLANT TEMP)

(a) Connect an intelligent tester to the DLC3.

(b) Turn the ignition switch ON.

(d) Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / PRIMARY / COOLANT TEMP.

(e) Read the COOLANT TEMP twice, when the engine is both cold and warmed up.

Standard:

With cold engine: Same as ambient air temperature.

With warm engine: Between 80°C and 100°C (176F and 212°F).

REPLACE ENGINE COOLANT TEMPERATURE SENSOR

READ VALUE OF INTELLIGENT TESTER (MAF)

Connect an intelligent tester to the DLC3. Turn the ignition switch ON. Turn the tester ON.

Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / PRIMARY / MAF and COOLANT TEMP.

Allow the engine to idle until the COOLANT TEMP reaches 75°C (167°F) or more.

Read the MAF with the engine in an idling condition and at an engine speed of 2,500 rpm.

Standard:

MAF while engine idling: Between 3.2 g/sec and 4.7 g/sec (shift position: N, A/C: OFF). MAF at engine speed of 2,500 rpm: Between 13.1 g/ sec and 18.9 g/sec (shift position: N, A/C: OFF).

REPLACE MASS AIR FLOW METER
