I have a suzuki liana cng rxi 1.3 l Yellow light of engine shape is continuosly on in dash board. the car has a hard stsrting. what is the reason?

I was looking for the Owners manual to see if there is a wheel where you can adjust the brightness or turn the dash light illumination off altogether? I didn't find that, but I did find the service manual!

light is engine fault

first of all check for leakages in CNG piping, use soapy water for leak detection, check all the clamps for tightness. There is one rubber pipe going from reducer valve to the suction duct check its condition and leaks. if no leaks, then try cleaning MAF sensor (Mass Air Flow) installed on throttle body, also clean Lambda sensor installed in exhaust. Use correct type of cleaners. For more details u can email me at [email protected]

sorry, this car is not meant to be fast.

change the engine

Not sure if you have already figured this out- or just sold your car, but I have been having the same problem and had a bit of a search around forums etc. Looks like it is the Crank Angle Sensor which needs to be replaced. I am about to go and get my car fixed so fingers crossed this is the miracle cure. Here is a link to the forum discussion on the issue.

BANK 2 SENSOR

It is the check engine light, the computer has detected a fault, and has stored it in memory.
The vehicle needs to be connected to an OBDII handset to read the codes. If you live in the US, take it to any Auto Zone store and they will read off the codes for you, once you have the codes, you are on your way to finding the problem. This may be possible at other major auto parts stores but you will have to call your local store to confirm.

Hope this is of some help.
