Have the wheels or tyres been changed?
Hi
I have a problem with speedmeter in Chevrolet Kalos 2007y.
The speedometer lowers the speed.
For example, when driving 100km / h the speedometer shows 60km / h.
Diagnostics does not show any errors. In the ABS parameters, the speed is OK. However, in the engine's ecu parameters it is the same as on the speedometer.
I replaced the speed sensor on the gearbox. I checked the wiring. I took the gearboxes out and checked the sensor's gears. OK.
Has anyone encountered a speedometer fault in these cars? Only why even as a detachable counter and drive it the ECU engine controller shows low speed ???
Have the wheels or tyres been changed?
Thanks but the tyres and wheel are correct for this model. This is not the problem.
If you stand still is the pointer to zero or below?
Don't forget the magic button !
some years ago I had a Toyota in the workshop, the transmission was late changing gear right across
the range no fault codes stored. wasted a lot of time on speed sensors throttle pots ect. while out on
road test I noticed launch was reading 50 MPH and the speedo was reading 50 . the difference one
was MPH the other KPH, turned out to be a Japanese import with some gismo fitted behind the dash.
wondered if there if there was a connection
