vvel issues

SonicVQ

I feel your pain... This is the downside of DIY, sometimes it does cost more.

To reduce the number of different connector that need to be purchased for manufacturing, where possible the connectors are reused.

The connector on the VVEL and throttle body (RH06FB) is also used on the MAF and accelerator pedal.

This isn't a problem for Nissan as the trained techs know this or mark/note where the connector came from.


To understand what could have happened, I dug up the wiring diagram and had a look. On the throttle body connector, pins 1+2 have 12v to drive the throttle body motor.
On the VVEL connector, pins 1+2 are the 5v position sensor (variable resistor)

In a nutshell, 12v has been fed to the 5 volt position sensor (VVEL pin 1) and 12 volts has been shorted to ground (VVEL pin2)

As I see it, the VVEL module might of got smoked and/or the VVEL position sensor. You might want to check the voltage at the VVEL position sensor to verify the sensor. (see FSM for values and pin outs)

I wish you the best of luck getting this sorted out
