A 1999 Honda CV-R (LHD)
Engine: B20Z1 / 2.0 L / 4 cyl / DOHC
Fuel: Fuel Injection
Trans: M/T
Mileage: 46 214 km
Emissions: OBD-II Compliant (EOBD- ?)
VIN: JHLRD174OXC210401 
Symptoms: MIL Lamp on
Occurs: Always (Idle or drive) after 3 min if Engine On

Quote from Mitchell On-Demand: "...Connect Honda PGM Tester or OBD-II scan tool to 16-pin Data Link Connector (DLC). On CR-V DLC is located behind right side of center console..."
I don't find OBDII-connector on this car...
I hav't Honda PGM Tester (for read codes from 3-pin connector) and known where connect my CJII.
IMHO: this car no had OBDII- Data Link Connector (?).

For read codes (by using MIL), I short 2-pin service check connector, turn ignition switch to ON. DTC must be indicated by a series of long and short flashes on MIL. But MIL flashes permanently (once every three sec). After erase DTC's I read again - no MIL flash. If Engine is ON - after 3 min MIL lamp also ON...

Courtesy iATN technicians I know MIL-code "1" is too most ("equivalent") SAE-codes p0131 ("Primary HO2S-1 Low Voltage"). 
My Report:

Note: On all Screen Images Range: for t3 – 5 ms/div; k4 – 0.5 V/div;W2 - 1200rpm/div. 1. I check* HO2S output voltage during idle, acceleration and deceleration and with 2.500 rpm (See Images). Oxygen Sensor is O'k.

2. Fuel pressure at Idle: 240 kPa (with vacuum); 290 kPa (if disconnected and pinched vacuum to regulator). Pressure at Fuel Pump >5 Mpa. Fuel pressure in Fuel Rail is O'k.

3. I check O2S output voltage during is disconnected and pinched vacuum to regulator (area "B" in this Image). Voltage is more 0.9 volt!

4. Then I did checkup Exhaust system and has seen the bad fastening... (photo). Exhaust system had leak! 
The car was in failure and mechanics have not paid attention to deformation of a fragment (part) of a exhaust system (collector).

After "repair" (reconstruction to hermeticities) I erase codes and "All is O'k" - no codes (after Drive)  and car is like new again.
Thanks a lot for help to  iATN Support and personally

Year Model Service Connector Location , MIL-codes Honda

Locating 2-Pin Service Check Connector

For erase DTC Air Bag System I use this MES connector.

On a 1994 Honda Prelude I read code "12" (by flashing "S" Lampe) - "EGR Valve Lift Sensor is malfunction". Valve , wire, output voltage (with the engine at idle and apply 8 in Hg) were O'k. But if I check vacuum in hose from EGR Valve (with vacuum gauge) this hose had no vacuum. #16 hose had leak...
