Kia Troubleshooting Questions? Ask a Mechanic
Hello, reference voltage is supplied by the ECM, but the wire can also short to a power wire causing this. What's the code that's coming up so I can provide you the troubleshooting info.
Hi Im David. give me a minute to look up some info. thanks
why are you replacing the crank sensor 3 times with a P0330 code?
so, it starts each time you replace it? the code is for the knock sensor
ok. give me a moment thanks.
ok, since a new sensor didnt fix the issue, its going to be a wiring issue. do you have a multi meter and are you able to get to the connector to the crank position sensor?
ok. we can check for the correct power and signal reference and ground. give me a moment to get a diagram
heres a wiring print of the system for starters. i will get the information on the pin out readings
check for a ground on pin 2 of the wiring connector. check for reference voltage on pin 3
the reference voltage should be 5vdc
if all of that tests ok. you will need to disconnect the ecm connector and we will need to check for continuity and high resistance shorts to ground on all 3 wires
i dont understand what you are saying
you are looking for voltage between the pins. you are looking for voltage at 1 and 3. dont use 2 as the ground use the negative battery post. are you back probing the connector with it connected? then check 2 for a good ground using the negative battery cable.
good now do this test
im sorry. ok. get better.
