Bank1 Oil Control Valve Connector Broken


Recommended Posts

Hello, I recently got a p1349 code on my 2001 ls430. My oil control valve is not functioning in that it does not extent when connected directly to the battery. Unfortunately, when I took the connector off, the wires came off the connector plug. Both wires are the same color-- dark-green with yellow stripe. I purchased a new plug (and valve) but don't know how to wire it up. Since it only involves two wires, does it matter how I hook them up to the plug?

I've attached two jpics below-- The plug wires.jpg is a pic of oil control valve wires from the wiring harness and the Connector.jpg is a pic of the newly purchased connector plug.

Any Ideas on how to determine which specific wire from the wiring harness goes to the connector plug wire or if it matters?

Ok with no response, I just hooked up the new plug. It appears to work as the p1349 and a new code p1565 (i Think). They are both gone. Nothing but smooth shifting. However, I now have a Check VSC light with no OBDii codes. So I used the jumper/dlc3 method and determined the code to be 39. I tried the use the zero point calibration but it does not work. Any suggestions.

Sometimes you have to reset the VSC system after engine maintenance; I had to do it after they replaced an oxygen sensor.

You'll need a paper clip and it's best to park the car on a level surface. You have to shove it into 2 ports on the connector under the dash.

Here's the thread:


Let us know if this solves the issue.
