    New Member needs help - can someone check if blue/white wire to EGR VSV is meant to be earthed to gound

    You were a great help - the wiring diagram you sent solved it! Until then I was not sure if it was a straight wire run from the ECM to the VSV. This is an awesome forum. Best wishes for your projects.

    New Member needs help - can someone check if blue/white wire to EGR VSV is meant to be earthed to gound

    PROBLEM SOLVED: Took the throttle body off and saw where the loom had been chafing. It was underneath and hidden - very cryptic. Only one short - as predicted - the Blue/White wire going to the EGR VSV. Will run a new wire from the ECU connector which should solve the problem. So to add to...

    Hi Greentruck - I have continuity in the VSV EGR wire from the ECU end to the VSV connector FZ1 - so there is no break. However I also get continuity with the chassis ground when I test from either end (ECU or Connector side). That doesn't seem right. The wiring loom is all original and...

    Hi NLXTACY - thanks for taking the time to send me the FSM test procedure and the wiring diagram. I went through the FSM tests as shown and everything checked out. The VSV, EGR, modulator all operated correctly. That is when I started looking at the wiring inputs. What I think is the problem...

    Greentruck -thanks for the reply - much appreciated. Yes I am grounding to the chassis in this test. What I don't understand is why I have ground on the EGR VSV Blue/white wire under all conditions even when the connector is removed from the ECU. This would imply that the ECU does not control...

    Can anyone help? I don't want to cut my loom until I am sure that the EGR VSV wire is not meant to be earthed. The 4 pin connector (FZ1) is on the top of the manifold in front of the Throttle Position Sensor so is visible and easily accessible. This connector feeds the EGR VSV and the Fuel...

    I am a newbie to this forum so please be gentle. My 86 FZJ80 LC threw the dreaded P0402 code – excess EGR flow. Went through the forum to glean wisdom and checked all the obvious suspects: VSV, EGR modulator, EGR valve all check out. All new hoses and vacuums present where they are supposed...
