Im from south india but in india all dealerships are closed there is no source to get parts and services from authorised dealerWelcome.....what part of India ?? A rather large country.
Phase sensor error is frequently caused by a disagreement between signals from the crankshaft sensor and the manifold pressure sensor. That disagreement happens when the starter clutch (sprag) is slipping. The ECU cannot decide when to fire the spark plugs or the injectors.
When the sprag is not the problem then the manifold pressure sensor likely has an air leak in the hose. Of course, the sensor itself could have failed, but that is not likely as this is an automotive type component designed to last many years and many thousands of miles.
