1. Open the hood of your Tata Indica.
2. Locate the engine.
3. Look for the transmission casing, which is typically at the bottom of the engine towards the front of the vehicle.
4. Follow the transmission casing until you find the area where it meets the engine.
5. The crankshaft position sensor is usually located near this junction, either on the engine side or the transmission side. It's typically a cylindrical-shaped sensor with one or two wires connected to it.
Please note that the exact location of the crankshaft position sensor may vary slightly depending on the specific year and model of your Tata Indica. If you are unable to find it, it's recommended to refer to the vehicle's service manual or consult with a qualified mechanic for assistance.
