Distributor HONDA INTEGRA 1998 4.G Workshop Manual

Valve Seals
Replacement (cylinder head removal not required)
The procedure shown below applies when using the in-
car valve spring compressor (Snap-on YA8845 with
Y AAA45-2A 1 /8" attachment).
!@@ When using this tool, as with any tool,
always use approved eye protection. Using the
fight tool tor each job helps increase productivity
while safeguarding tools, equipment and ihe user.
Turn the crankshaft so that the No. 1 and the No. 4pistons are at top dead center (TDC).
Remove the cylinder head cover.
Remove the distributor.
Loosen and disconnect the timinq belt from the
camshaft oullevs.
5. Remove the camshaft holder bolts, then remove the
camshaft holders, the camshafts and rocker arms.
Intake Valve Seals
6. Using the 6 mm bolts supplied with the tool, mount
the two uprights to the cylinder head at the end
camshaft holders. The uprights fit as shown.
7. Insert the cross shaft through the bottom hole of
the two uprights.
8.
9.
10.
Select the 7/8 in. diameter long compressor attach-
ment and fasten the attachment to the No. 4 hole of
the lever arm with the speed pin supplied.
Position the piston at TDC and insen an air adaptor
into the spark plug hole. Pump air into the cylinder
to keep the valve closed while compressing springs
and removing the valve keepers.
Position the lever arm under the cross shaft so the
lever is perpendicular to the shaft and the compres-
sor attachment rests on top of the retainer for the
spring being compressed. Use the rear position slot
on the lever as shown.
NOTE: Put shop towels over the oil passages toprevent the valve keepers from falling into the cylin-
der head.

Random Misfire
1T0-500 1 a nd Fo-30ittrrousFF0304-lThB scan tool indicates Diagnostic Trouble Code {DTC) P0300 and some of
P0301 - P0304: Random misfire.
Doscription
Misfir; detection is accomplished by monitoring the crankshaft speed with the crankshaft speed fluciuation sensor which
is attached to the crankshsft.
lf misfiring strong enough to damage the catalyst is detected, the MIL will blink during iho time of its occurrence, and DTC
p0300 and some of DTCS p0301 through P0304 will be stor€d. Then, after misfire has ceased, the MIL will come on.
lf misfiring that increases emissions is detected during two consecutive driving cycles, the MIL will come on, and DTC
PO3O0 and some ot DTCS P0301 through P0304 will be stored
NOTE: lJ some of the DTCS listed below are stored at the same time as a misfire DTC, troubleshoot those DTCS first. then
troubleshoot the misfire DTC.
P0171, P0172: Fuel metering
P0505: ldle Control SYstem
P1361, P1362: TDC sensor
P1381. P1382: CYP sensor
P1508: IAC valve
Possible Cause
. Fuel pump insufficient fuel pressure. amount of flow
. Fuel line clogging, blockage, leakage
. Fuel {ilter clogging
a Fuel pressure regulator stuck open
. Distributormallunction
o lgnition coil wire open, leakage
. lgnition control module malfunction
. Valves carbon deposit
a Compression low
. IAC valve malfunction
. Fast idle thermo valve malfunction
o Fuel does not meet Owner's Manual spec., lackotfu€l
. VTEC system malfunction
Troubleshooting
By test-driving, determine the conditions during which misfire occurs. Depending on these conditions, test in the order
described in the table below.

Doscription
Misfire detection is accomplished by monitoring the crsnkshaft speed with the crankshaft speed fluctuation sensor whichis attached to the crankshaft.
lf misfiring strong enough to damage the catalyst is detected, the MIL will blink during the time of its occurrence, and DTCP0301, P0302, P0303 or P0304 will be stored. Then, after the m;sfire has ceased, the MIL witt come on.lf misfiring that increases emissions is detected during two consecutive driving cycles, the MIL will come on, and DTCP0301, P0302, P0303 or P0304 will be stored.
NOTE: lf some of the DTCS listed below are stored at the same time as a misfire DTC, troubleshoot those DTCS first, thentroubleshoot the misfi.e DTC.

Crankshaft Position/Top Dead Center/Cylinder Position (CKP/TDC/CYPI Sensor
The scan tool indicates Diagnostic Trouble Code {DTC) P0335: A malfunction in the Crankshaft Position (CKP)
sensor circuit.
The scan tool indicates Diagnostic Trouble Code (DTC) P0336: A range/performance problem in the CrankshaftPosition (CKP) sensor circuit.
The scan tool indicates Djagnostic Trouble Code (DTC) Pl361: Intermittent interruption in the Top Dead Center(TDC) sensor circuit.
The scan tool indicates Diagnostic Trouble Code (DTC) P1362: No signal in the Top Dead Center (TDC) sensorcircuit.
The scan tool indicates Diagnostic Trouble Code (DTC) P1381: Intermittent interruption in the Cylinder Position(CYP) sensor circuit.
The scan tool indicates Diagnostic Trouble Code (DTC) P]382: No signal in the Cylinder Position (CYP) sensorcircuit.
D€scription
The CKP Sensor determines timing for fuel injection and ignition of each cylinder and also detects engine speed. The TDCSensor determines ignition timing at stan-up (cranking) and when crank angle is abnormal. The Cyp Sensor detects theposition of No. 1 cylinder for sequential fuel injection to each cylinder.
NOTE: ll DTC P1359 is stored at the same time as DTC P0335, P0336, Pl361, P1362, P1381 and/or P1382. troubleshoot DTCP1359 first, then troubleshoot those DTCS.
