2. pull battery neg lug, and lose the radio , and nav. codes,
3. pull the ecu memory fuse. (no engine stated, so can answer)

you mean the firing order ...... for the drivers side its 135
the passengers side 246

what country? having the connector does NOT mean it complies
with USA OBD2 systems and tools, so not posting country , all answers are impossible. if you google the you will see that repeated like 1million times.
LHD or right hand drive?
if in USA, LHD all cars here are OBD2 16pin Dshell connectors.
and 100% OBD2 compliant.

Should be near the steering column on the bottom of the dash.

The check engine light is because all check engine light codes are caused by components that affect emissions. It's not actually an engine problem, it's a problem with either your O2 sensor, MAF sensor, fuel/air ratio, pyrometer, or exhaust.

obd2 scanner

420 is O2 sensor, this can happen from putting the wrong replacement sparkplugs in or just age of vehicle this just happened to my suzuki vitara so i replaced the plugs ($18) and the code hasnt come up again yet. if it does come up again ill do the sensor ($180). prices indicated are do it yourself prices

Do the following:
-Check the clutch fluid,
-With the engine off make the trip from 1 to 5 gear,as if you were on the road
if it is okay
Let's go to the second step, With the engine running, do the same but keeping the pedal depressed , Does not engage any gear ?
-If the clutch fluid is OK , then The bearing of the output shaft is damaged or clutch release bearing

Take the car to an autoparts store and have them scan the computer for any fault codes stored. The check engine light is to alert you that the computer has noted a fault in one of the car's systems. Getting the codes will show what the computer has noted and curb the need for speculation. Most parts stores will perform the scan for free. Hope this helped and best wishes.

Try these easy things...take off clean and reconnect the battery cables, take to Auto Zone for a FREE computer hook up. More than likely if the battery hook up doesn't work it's the oxygen sensor.
