Question

Hi,

The fuel pump was replaced, then I get the error code P1389. ASD Relay changed. continues error code?

Answer 1

HI there

The ASD relay is grounded by the computer. If there is an issue with the cam or crank sensor, it will not ground the relay. You could also have an issue with the power source for the relay or the ecm itself.
