OOPS Check the frequency valve itself. It's simply a solenoid. Should measure 2 to 3 ohms.
Also, was it running previously? Or is this a restoration of a long idle car? If long idle perhaps a sharp rap or 2 to dislodge a mechanically frozen valve? Gotta run. See if MY old CIS is running correctly! No wait a minute. "This checked out fine. We had 12v to the FV from the lambda relay side. When we tested the computer side, we read a constant +.5v. It could have been switching fast enough that the multimeter wasnt keeping up. " This would indicate the FV is constantly ON. The .5V is reasonable for a solid state swtiching device (transistor). If the FV was switched OFF then there would be 12V on both sides as there would be no current flow. What does this mean? I really don't know. The resting state of the computer could be ON for all I know. When I return this afternoon I will review the trouble shooting guide and share it also. Look for the power and squarewave output on the computer test lead. |
