Starting System
Starter Test
NOTE: The air temperature must be between 59 and'100'F (15 and 38"C) before testing.
Recommended Procedure:
. Use a staner system tester.
. Connect and operate the equipment in accordance
with the manufacturer's instructions.
. Test and troubleshoot as described.
Alte.nate Procedure:
. Use the following equipment:- Ammeter, 0 - 400 A- Voltmeter, 0 - 20 V (accurate within 0.1 volt)
Tachometer,0 - 1,200 rpm
. Hook up a voltmeter and ammeter as shown.
NOTE: After this test, or any subsequent repair. reset
the ECM/PCM to clear any codes (see section 1 1).
Check the Starter Engagement:
'1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box.
2. Turn the ignition switch to START (lll) with the shift
lever in E or E position (A/T) or with the clutch
pedal depressed {M/T). The starter should crank the
eng ine.
. lf the starter does not crank the engine, go to
step 3.
. lf it cranks the engine erratically or too slowly, go
to "Check for Wear and Damage" on the next
page.

lf the staner still does not crank the engine, go to
step 4.
Unplug the connector (BLK /VHT wire and solenoid
terminal) from the starter.
Connect a jumper wire from the baftery positive (+)
terminal to the solenoid terminal.
The starter should crank the engine.
. lf the starter still does not crank the engine,
remove it, and diagnose its internal problem.
. lf the starter cranks the engine, go to step 6.
Check the ignition switch (see section 23).
Check the starter cut relay {see section 23}.
Check the IVT gear position switch (A/T) or the clutch
interlock switch (M[).
Check for an open in the wire between the ignition
switch and starter.

ll. Engine Controt Module (EcM)/Powertrain Control Module {PCM) Reset Procedure
Either of the following actions will reset the ECM/PCM.
. use the oBD ll scan tool or Honda PGM Tester to clear the ECM' s/PCM' s memory. (see the oBD ll scan tool or
Honda PGM Tester user's manuals for specific operating instructions )
. Turn the ignition switch oFF. Remove the BACK UP (RADIO) (7.5 A) fuse from the under-hood fuse/relay box for 10
seconos.
lll. Final Procedure {this procedure must be done after any troubleshooting)
1. Remove the SCS Service Connector if it is connected. lf the SCS service connector is connected. and there are no
DTCS stored in the ECM/PCM, the MIL will stay on when the ignition switch is turnsd oN (ll).
2. Do the ECM/PCM Reset Procedure.
3. Turn the ignition switch OFF
4. Disconnect the OBD ll scan tool orHonda PGM Tester from the Data Link Connector ( 16P)'

How to Read Flowcharts
A flowchart is designed to be used from start to final repair. lt's like a map showing you the shortest distance. But beware:
lf you go off the "map" anywhere but a "stop" symbol, you can easily get lost.
brARn
t.-OotO tw"t Describes the conditions or situation to start a troubleshooting flowchart.
FcTloNl Asks you to do something; perform a test, set up a condition etc.
@ Asks you about the result of an action, then sends you in the appropriate troubleshooting direction.
fS-OPl The end of a series of actions and decisions, describes a final repair action and sometimes directs you to
(bold type) an earlier part of the flowchart to confirm your repair.
NOTE:
. The term "lntermittent Failure" is used in these charts. lt simply means a system may have had a failure, but it checks
out OK at this time. lf the Malfunction Indicator Lamp (MlL) on the dash does not come on, check for poor connections
or loose wires at all connectors related to the circuit that you are troubleshooting (see illustration below).
. Most of the troubleshooting flowcharts have you reset the Engine Control Module (EcM)/Powertrain Control Module(PCM) and try to duplicate the Diagnostic Trouble Code (DTC). lf the problem is intermittent and you can't duplicate the
code, do not continue though the flowchart. To do so will only result in confusion and, possibly, a needlessly replaced
ECM/PCM,
o "Open" and "Short" are common electrical terms. An open is a break in a wire or at a connection. A short is an acci-
dental connection of a wire to ground or to another wire. ln simple electronics, this usually means something won't
work at all. In complex electronics (like ECM'S/PCM'S), this can sometimes mean something works, but not the way it's
suooosed to.

Primary Heated Oxygen Sensor (Primary HO2S) (Sensor 1)
The Heated Oxygen Sensors (HO2S) detect the oxygen content in the exhaust gas and signal the ECM/PCM. In operation,
the ECM/PCM receives the signals from the sensor and varies the duration during which fuel is iniected. To stabilize the
sensor's output, the sensor has an internal heater. The Primary HO2S (Sensor 1) is installed in exhaust pipe A.

tFO133 lhe scan tool indicates Diagnostic Trouble Code (DTC) P0133: A slow response problem in the Primary Heated: Oxysen Sensor (Primarv HO2S (Sensor 1) circuit.
Description
By controlling the airlfuel ratio with a Primary HO2S (Sensor 1) and a Secondary HO2S (Sensor 2), the deterioration of the
Primary HO2S (Sensor 1) can be evaluated by its feedback period. When the feedback period of the HO2S exceeds a cer
tain value during stable driving conditions, the sensor will be judged as deteriorated.
When deterioration has been detected during two consecutive trips, the MIL comes on and DTC P0133 will be stored.
NOTE: lf DTC P0131, P0132 and/or P0135 are stored at the same time as DTC P0133. troubleshoot those DTCS first, then
troubleshoot DTC P0133.
Possible Cause
. Primary HO2S (Sensor 1) Deterioration
. Primary HO2S Heater (Sensor 1) Deterioration
