The original Piaggio coolant temperature sensor, code 8942287102000, is the thermistor screwed into the cooling circuit of the Porter 1300 16V with a Daihatsu HC engine. It reads the water temperature and transmits it to the engine management system and instrumentation. It has a hexagonal brass body with a threaded tip and a gray two-way connector (as seen in product photographs). When it fails, the dashboard goes haywire: the needle stays at the bottom or never rises, the warning light comes on, and fuel consumption increases because the ECU continues to believe the engine is cold.
✓ Strengths
- Original Piaggio Group spare part, code 8942287102000 — not an aftermarket equivalent
- Original connector: plugs into the standard wiring, without adapters or splices
- Direct fit: screws in place of the old one, takes just a few minutes
- This is the correct part for the Daihatsu HC engine of the Porter 1300 16V petrol, LPG, and methane models
- A healthy sensor restores fuel consumption: the ECU stops enriching the mixture as if the engine were cold
- New product, shipped from an official Piaggio and Aprilia dealer

⚠️ Important notes:
- Before replacing, rule out wiring issues. Half of the erratic readings on the Porter come from oxidized connectors or a broken wire, not the sensor itself. Check the resistance between the two pins when the engine is cold and when it's hot: if it changes regularly, the sensor is working.
- The circuit must be refilled and bled after the intervention: coolant will escape when the sensor is unscrewed, and the Porter has long pipes that retain air.
- Screw in without forcing: the body is brass, and the seat is aluminum or cast iron: excessive tightening will damage the thread of the seat, which costs much more than the sensor.
- The Porter has multiple sensors on the water circuit (temperature, fan thermo-switch, warning light bulb). Verify the code stamped on the mounted part or the VIN before ordering.

Who is it perfect for?
For those with an Up-Date Porter that consumes more than it should, has the fan always on, or has the temperature gauge doing whatever it wants. It's a small part with enormous specific weight on the vehicle's behavior: the ECU decides how much fuel to inject based on what this sensor tells it, and if the story is wrong, the van guzzles fuel and runs poorly when cold. Changing it is among the interventions with the best cost-to-result ratio on the entire Porter.
Frequently Asked Questions
How do I know if the sensor is faulty?
Typical symptoms: temperature gauge stuck on cold or bottomed out, fan starts immediately or never, difficult hot starting, unexplained increase in fuel consumption. Confirmation comes with a tester: the resistance between the two pins should decrease as the engine warms up.
Is this the sensor for the ECU or the dashboard?
It has a two-way connector: it reads the coolant temperature for engine management, and the dashboard indication also depends on that reading.
Do I also need to change the O-ring?
The seal is on the threaded seat of the sensor itself. If the mounted part was leaking, check that the seat on the engine is clean and intact before screwing it back in.
Is it suitable for LPG or methane Porter models?
Yes: the official catalog indicates this code for the Porter Up-Date and Maxxi Up-Date 2009-2010 in petrol, LPG, and methane versions — the engine is the same.
Does the shipment originate from Italy?
Yes. We ship from Cercola, in the province of Naples, with tracked courier.
