Is it dangerous to drive with this sensor faulty?

Not directly dangerous, but it can lead to incorrect DPF management, potentially causing the filter to clog prematurely — repair promptly.

Can this sensor be cleaned instead of replaced?

The sensor itself is rarely the issue when clogged — more often the small pressure pipes leading to it get blocked with soot, which is worth checking and clearing first.

What is the sensor made of?

A pressure-sensing diaphragm element in a heat-resistant housing.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
