My car has a faulty speedo cable coming from the gearbox, i cant rev my car because the check engine light is on due to the speedo cable/sensor.

is there a way to bypass the sensor so the car will run fine with no check engine light ?

Like put a resistor or sumit in the sensor?

 

No. The ECU needs the speed sensor input to control the engine properly. The car won't run correctly without it.

 

dcoes the gearbox need to be removed to replace the short end of the speedo cable?
