My sensor light is on and how to reset that? Mitsubishi Challenge

Small piece of black electrical tape carefully located is the easy way, or if you like a challenge you could remove the offensive bulb.

reset is by the OBD reader , that is what read the code there will be a code clear/reset function

there should be 4 sensors in the system two are normal O2 sensors that are located after the cat converter and two are heated sensors HO2S sensors located before the cat converter. Use the special sensor removal/installer tool so that the wires are not damaged . If you only replace d 2 sensors then you may have missed the faulty unit. The check engine light will stay on until you reset it with a scanner

the camshaft position sensor is located behind the harmonice balancer remove balancer and timing cover once removed you will see it u will also have to remove the crank gear and timing belt be sure to reset the timing or mark the gears before removal hope this helps

Contact a Mitsubishi dealer for advise , could need a new ecu , hard to say without seeing vehicle

this light will go out after you inflate the tires to the proper pressure, make sure to check the spare tire also as sometimes they may have a sensor on them too.after all tires are set you may need to drive a few miles to reset the light. if the light remains on then you may have a bad sensor and will have to go and have each sensor tested with a tpms tool. the manufactor lists 10min of driving after setting all tire pressures even the spare tire and then light will go out. good day.

If you have a 4 cylinder, all sensors can be accessed from the ground. They are mounted above and below the exhaust manifold, in plain sight.

If you have a V6, the bank 1 sensor 1 and bank 2 sensor 1 can be accessed from the ground, they are located at the top of each exhaust manifold. Both sensor 2's (the ones after the catalytic converters) must be accessed with the vehicle lifted.

To change the sensors out, a proper O2 sensor socket is desirable. If one is not available, the sensor nut is 22mm, but you may have difficulty getting a wrench to work in the limited space available.

I only recommend genuine Mitsubishi/Denso sensors, as they are just plain more reliable. If you do buy aftermarket, be sure they are complete sensors, not cut and splice sensors.

You can unhook the negative battery cable for 5 minutes to reset the light, or use a scantool (Autozone and similar will often reset your light for free).

man this one was a challenge. however i did learn that this vehicle is autralian. pretty cool i might add. however the symbal is basically the same thing as a check engine light. took me 2 hours to find that answer for ya.

have you had the car scanned for codes? the light could be on for something other than the o2 sensor

If you have changed out the parts and still get the codes you probably need to have the ECM reset. The dealer can do that for you or a repair shop that has the scan tool.
