service reset HONDA CR-V 1999 RD1-RD3 / 1.G Workshop Manual

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)'

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
. Exhaust system leakage

NOTE:
. Disconnecting the BACK Up fuse also cancels the radio preset stations and clock setting Make note of the radio
presets before removing the fuse so you can reset them
. The PCM memorv can also be cleared by using the OBD ll Scan Tool or Honda PGM Tester'
UNDER.HOODFUSE/RELAY BOX
Final Proceduro
This procedure must be done after any troubleshooting.
1. Turn the ignition switch OFF.

Turn the ignition switch ON {ll), then set the mode control dial to the Vent position, and the recirculation controt switch toRecirculate {recirculation indicator light comes on). Press and hold the recirculation control switch to Fresh (recirculation indi-cator light goes off). Continue to hold the switch; the recirculation indicator light will come on for two seconds. then it willblink the Diagnostic Trouble Code (DTC) to indicate a iaulty component. lf no DTC'S are found, the indicator liqht will notblink atter the initial two second light.
