Fiat Punto won't start - Camshaft sensor problem?

Hello everyone, I have a 2004 Fiat Punto with a gasoline engine and 110,000 km mileage. The check engine light came on and the car wouldn't start. After about 2 hours I could start it again and drive it home, but afterwards it wouldn't start again. The starter turns perfectly and there is enough fuel. Could the problem be related to the camshaft sensor, possibly contact problems? Can you measure this sensor with a multimeter? Thanks in advance for your support.

A 2004 Fiat Punto with a gasoline engine experienced a starting issue, with the check engine light on, despite the starter working and sufficient fuel. The problem might be linked to the camshaft sensor, possibly due to contact issues. It was suggested to measure the sensor's resistance with a multimeter and check for wiring damage. After cleaning the sensor contacts and securing the wiring harness, the car started again, though it's uncertain if the issue is permanently resolved.

Yes, you can measure the camshaft sensor with a multimeter to check for any issues. Set the multimeter to measure resistance (ohms) and disconnect the sensor's electrical connector. Measure the resistance across the sensor's terminals and compare it to the specifications in your vehicle's repair manual. If the resistance is outside the specified range, the sensor may be faulty. If the sensor seems fine, check the wiring and connections for any signs of damage or corrosion. Let me know how it goes or if you have any further questions!

Thank you for the quick advice with the multimeter. When the weather is better I will go searching (or hunting) and get back to you. All the best to you!

Unfortunately, I don't have a workshop manual with the technical data for the sensor for the Punto 188, 1.2l 8V. Do you have a recommendation for me?

You can often find the specifications for the camshaft sensor in online forums or by searching for a digital version of the workshop manual specific to your Fiat Punto model. Alternatively, you can contact a Fiat dealership or a local auto parts store for the sensor's resistance specifications. If you need further assistance, feel free to ask!

You might also consider checking online resources like repair websites or automotive databases that offer repair guides and specifications for various car models. If you manage to find the specifications and perform the test, let me know how it goes or if you have any further questions!

So, the sensor on the 188 Punto was removed and measured (approx. 180 kOhm & 0.7 megaOhm), the contacts on the connector and sensor were cleaned, a missing strain relief on the wiring harness was installed: It starts immediately again! Whether the problem is permanently solved, I can't say for sure yet, that takes time. Thanks again for the helpful support, best regards Schrauber_Joe

It's great to hear that your car is starting again! Keep an eye on it to see if the issue reoccurs. If the problem persists, consider checking other related components like the crankshaft sensor or ignition system. Feel free to reach out if you have any more questions or need further assistance. Safe driving!
