It might seem easy to integrate a sensor that detects the opening/closing of a mechanical thermostat's pintle (LVDT, for example) but here are some challenges which would need to be addressed: Cost vs Benefit Is a "smart" thermostat really worth the extra hassle and money when its dumb counterpart has the following to offer? : it's already ...

There is a distinction that needs to be made between: OBD: this is an interface, that specifies the physical and electrical parameters required to connect a diagnostic computer and the car's electronics in a standard way. This is the bit that is mandatory by legal requirement, so that a car manufacturer cannot "lock in" its vehicles by requiring service to ...

I suspect that the sensors were detecting the loose paint as an object very close. You should be able to re-paint them, but I don't know if they would need a special sort of paint - it might be worth checking with Ford

I don't think CAN is a necessary part of OBD, it's just the most commonly used system. The OBD requirements are for consistent diagnostics (so that, in theory, any car can be plugged into a standard reader and give a standard set of error codes), wheras CAN is a method for the internal components of the car to communicate (similar in many ways to the USB ...

None of this is true. In the same way as there was an EU Directive that all cars be equipped with ABS but TVR didn't subscribe to this. My uncle has just sold a 2005 Caterham Se7en CSR-200 which used MBE management and was definitely not CAN-BUS. We're building another one in October of this year and if it genuinely is CAN-BUS I'll let you know but I have ...

OBD is a standard for a diagnostics port that provides emissions-related info on the diagnostics port. Contrary to popular belief its purpose isn't to prevent lock-in by car manufacturers but only to allow service centers a standard way to access emissions-related info required for mandatory checks like the "MOT test" (as they call it in the UK). The ...

The two requirements are separate. OBDII is required in all vehicles since 1996. This is primarily an emissions related regulation to formalize how vehicles would relay emissions failures to the user and to mechanics. The standard has many parts, but it primarily designated a connector, its pinout, and allowed one of five different electrical signalling ...

How is the OBD and CAN exactly related? Controller Area Network (CAN) is ISO 11898 standard. It, like most other networks, is based off of the OSI model. It specifies certain parameters for communications between vehicle systems. CAN was first specified in 1986 by Robert Bosch at the Society of Automotive Engineers (SAE) congress. CAN uses serial ...

Some tire pressure sensors are not in the tire, but part of the anti-lock brake system. The wheel speed sensor is used to track the rotation of the tire. When it becomes out of sync with the other three, it shows on the dash as a low tire indication (I don't know what the differential has to be to register, though I bet it is manufacturer dependent). What ...

As per your question the issue is about overheating. For that we already have a coolant temperature sensor, which can alert the driver when there is over heating. For your kind information there are electrically controlled thermostats in some modern engines of Mercedes and maybe in some others too!!!
