HLA TROUBLESHOOTING GUIDE

HLA Troubleshooting Guide

Problem	Possible Cause	Action
1. Noise when engine is first started after oil is changed. 2. Noise when engine is started after setting approx. one day. 3. Noise when engine is started after cranking for 3 seconds or more. 4. Noise when engine is started after new HLA is installed.	Insufficient oil in HLA; Oil leakage from HLA	Run engine at 2,000-3,000 rpm. If noise stops after 2 seconds-10 minutes,* HLA is normal. If not, replace HLA. * Time required for engine oil to circulate within engine includes tolerance for engine oil condition and ambient temperature.
5. Noise continues more than 10 minutes.	Insufficient oil pressure	Check oil pressure. If lower than specification, check for cause. Oil pressure: 334-490 kPa {3.4-5.0 kgf/cm2, 49-71 psi}-3,000 rpm
5. Noise continues more than 10 minutes.	Faulty HLA	(Refer to page B2-79.) Press down HLA by hand. If it does not move, HLA is normal. If it moves, replace HLA. Measure valve clearance. If more than 0mm {0 in}, replace HLA.
6. Noise during idle after high speed running.	Incorrect oil amount	Check oil level. Drain or add oil as necessary.
6. Noise during idle after high speed running.	Deteriorated oil	Check oil quality. If deteriorated, replace with specified type and amount of oil.

1. Noise when engine is first started after oil is changed. 2. Noise when engine is started after setting approx. one day. 3. Noise when engine is started after cranking for 3 seconds or more. 4. Noise when engine is started after new HLA is installed.

Possible CauseInsufficient oil in HLA; Oil leakage from HLA

ActionRun engine at 2,000-3,000 rpm. If noise stops after 2 seconds-10 minutes,* HLA is normal. If not, replace HLA. * Time required for engine oil to circulate within engine includes tolerance for engine oil condition and ambient temperature.

5. Noise continues more than 10 minutes.

Possible CauseInsufficient oil pressure

ActionCheck oil pressure. If lower than specification, check for cause. Oil pressure: 334-490 kPa {3.4-5.0 kgf/cm2, 49-71 psi}-3,000 rpm

5. Noise continues more than 10 minutes.

Possible CauseFaulty HLA

Action(Refer to page B2-79.) Press down HLA by hand. If it does not move, HLA is normal. If it moves, replace HLA. Measure valve clearance. If more than 0mm {0 in}, replace HLA.

6. Noise during idle after high speed running.

Possible CauseIncorrect oil amount

ActionCheck oil level. Drain or add oil as necessary.

6. Noise during idle after high speed running.

Possible CauseDeteriorated oil

ActionCheck oil quality. If deteriorated, replace with specified type and amount of oil.

IGNITION TIMING, IDLE SPEED

Preparation

1
Warm up the engine to normal operating temperature.
2
Turn all electric loads off: Headlight switch, Blower switch, Rear window defroster switch.
3
Connect the SST to the data link connector.
4
Connect a timing light.
5
Connect a tachometer to the data link connector terminal IG-.

Ignition timing

1
Perform "Preparation." (Refer to above.)
2
Make sure the idle speed is within the specification. If not, adjust the idle speed. Idle speed (MTX in Neutral, ATX in P range): 650-710 rpm.
3
Set switch (A) to position 1.
4
Set TEST SW to SELF-TEST.
5
If the SST is not used, jump across the TEN and GND terminals of the data link connector.
6
Make sure the timing mark (yellow) on the crankshaft pulley and the mark on the timing belt cover are aligned. Ignition timing: 9-11° BTDC.
