Engine mounting HONDA CR-V 2000 RD1-RD3 / 1.G Workshop Manual

Starting System
Starter Test (cont'dl
Check lor Wear and D8mage
The starter should crank the engine smoothly and
steadily. lf the staner engages, but cranks the engine
erratically, remove it, and inspect the starter drive gear
and torque converter ring gear or flywheel ring gear for
oamage.
Check the drive gear overrunning clutch for binding or
slipping when the armature is rotated with the drive
gear held. lf damaged, replace the gears.
Check Cranking Voltage and Current Draw
Cranking voltage should be no less than 8.7 volts on Ay'T
models, and 8.0 volts on M/T moders.
Current draw should be no more than 230 amperes on
A,/T models, and 200 amperes on M/T models.
lf cranking voltage is too low, or current draw too high,
check for:
. dead or low battery.
a open circuit in starter armature commutator seg,
ments.
. starter armature dragging.
. shorted armature winding.
. excessive drag in engine.
Check Cranking rpm
Engine speed during cranking should be above 100 rpm.
lf speed is too low, check for:
a loose baftery or starter terminals.
. excesslvely worn staner brushes
. open circuit in commutator segments.
. dirty or damaged helical splines or drive gear.
a defective drive gear overrunning clutch.
Check Starter Disengagement
With the shift lever in @ or @ position (A,iT) or with the
clutch pedal depressed {M/T). turn the ignition switch to
START (lll). and release to ON (ll).
The starter drive gear should disengage from the torque
converter ring gear or flywheel ring gear when you
release the key.
lf the drive gear hangs up on the torque converter ring
gear or flywheel ring gear, check for
. solenoid plunger and switch malfunction.
. dirty drive gear assembly or damaged overrunning
clutch.
Starter Solenoid Test
1. Check the hold-in coil for continuity between the S
terminal and lhe armature housing (ground). The
coil is OK if there is continuity.

1.Check the idle speed, and adjust it if necessary (see
section 1 1).
Pull out the service check connector 2P (BRN and
BLK wires) from the connector holder located under
the dash on the front passenger side, then connect
the scs service connector (P/N 07PAz - 0010100) to
it.
Start the engine. Hold the engine at 3,000 rpm with
no load (A/T in N or E, Mff in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. I ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights, blower fan, rear window defogger, and
air conditioner are not operating.

Removal
Engine removal is not required for this procedure.
l!@ Make sure iacks and safety stands are
placed properly, and hoist blackels ale attachgd to the
correct position on the engine.
NOTE:
o Use fender covers to avoid damaging painted sur-
faces.
o To avoid damage, unplug the wiring connectors care-
fully while holding the connector portion.
. To avoid damaging the cylinder head, wait until the
engine coolant temperature drops below 100"F (38'C)
before loosening the retaining bolts.
. Mark all wiring and hoses to avoid misconnection.
Also, be sure that they do not contact other wiring or
hoses, or interfere with other parts.

ldle Control System
System Description
The idle speed of the engjne is controlled by the ldle Air Control (lAC) Valve'
The valve changes the amount of air bypassing into the intake manifold in response to electric current controlled by the
ECM/PCM. When the lAc valve is activated, the valve opens to maintain the proper idle speed.
YEL/ From PGM'FI
BLK TMAIN RELAY
VARIOUSSENSORS
4.
IAC VALVE
INTAKE MANIFOLD
After the engine starts, the IAC valve opens for a certain time. The amount of air is increased to raise the idle speed
about 150 - 300 rpm.
when the cootant temperature ts row, the lAc valve is opened to obtain the proper fast idle speed The amount o{
bvoassed air is thus controlled in relation to the engine coolant temperature
When the idle speed is out o{ specification and the scan tool does not indicate Diagnostic Trouble Code (DTC) P0505
or P1508, check the following items:
. Adjust the idle speed (see page 11-169, 170)
. Air conditioning signal (seepagell-1551
. ALT FR signal (see page 1l-159)
. Starter switch signal (see page 11-16'1)
. A,/T gear position signal (see section 14)
. PSP switch signal (seepagell-162)
. Brake switch signal (see page 11-165)
. Fast idlethermovalve (see page'11 168)
. Hoses and connecttons. IAC valve and its mounting O-rings
lf the above items are normat, suDslitute a known-good IAC valve and readjust the idle speed {see page 11-169, 170)
lf the idle speed still cannot be adjusted to specification (and the scan tool does not indicate DTC P0505 or Pl508)
after IAC valve reolacement, substitute a known-good ECM/PCM and recheck lf symptom goes away' replace the
original ECM/PCM.
