Is a TDC sensor a camshaft sensor?
RPM sensor and the crank sensor are the same not just in Palio but in all cars. Cam sensor and TDC sensor (if it exists) should be the same also. Cam sensor and Crank sensor are not the same. The Cam sensor is mounted on the Cam shaft and Crank sensor on the crankshaft.
What is the function of the TDC sensor?
The function of the Top Dead Centre Piston Sensor (TDC) is similar to that of the CKP (Crankshaft Position Sensor), unlike the latter detects the position of each cylinder, while the TDC sensor determines the position of the piston in the cylinder when it starts the vehicle.
Can a multimeter be used to test a CKP sensor?
So, it is important to test the CKP to better diagnose the problem. Although it’s recommended to test a CKP sensor using an oscilloscope, this is not a common tool for many car owners or DIYers. Still, you can troubleshoot the sensor using a digital multimeter (DMM), whether your engine uses an inductive or Hall effect type sensor.
When to replace the crankshaft position sensor ( CKP )?
If your reading is not close to the recommended resistance, then you should replace the sensor. Another way to test the crankshaft position sensor (CKP) is with a multimeter. You do this by checking the output voltage with the engine cranking. You will need an assistant to do this.
What should the CKP sensor read on the ignition?
You may need to check the wiring diagram for your particular model, if the CKP sensor uses wires of different color to identify the ground, power and signal wires. Turn the ignition key to the On position. Your meter should read between 5 and 13 volts. Consult your vehicle repair manual for the reference voltage value for your particular model.

What does the crankshaft position sensor ( CKP ) do?
So, The crankshaft position sensor (CKP) monitors as a multi functional sensor used to set ignition timing, detect engine (RPM) and relative engine speed. This sensor voids the need for manual distributor timing. Because, The sensor (CKP) is used to determine which cylinder is firing to synchronize the fuel injector and coil firing sequence.
What happens if the CKP is not accurate?
Without accurate input from the sensor (CKP), the (ECU) can not make these adjustments as well as it should. As a result, This causes poor acceleration and makes your car fail to maintain constant speed. Without accurate timing information fuel injection will have incorrect sensor (CKP) readings.
