Default Re: Fiesta problem - Speedo drops to Zero intermittently

Hi,

After replacing the speedo sensor on the top of the transmission, the car has not played up again.

It maybe worth getting a generic OBD reader (ELM127 dongle & app for phone) total cost about $40. This is what I did and read the code myself.

Came up with a missing speed signal.

Now the old sensor did have coolant that leaked on to it and may have caused the issue? Repaired the leaking coolant and replaced the sensor and cleared the codes. Been driving ok since.

Speed sensor about $30 from eBay.

Hope this helps!

Regards
