oil pressure readings

Greetings,

At normal throttle/rpm's (startup up, etc.) the oil pressure reads correctly, but at at WOT it shows 0 pressure. Any suggestions?

This looks to me like and electric- trick and not a mecahnical engine problme. First, I would check the cable attached to the pressure sensor. I have seen this when the cable within the connector or attacehd to teh sensor came lose, especially if it's intermittent. Also might want to check and change the sensor for a new one if it's not the cable.

Alex, thank you. It is a new sensor, replaced by MM 2 months ago. I'll check the connections. I too think it might be electrical and not an actual loss in pressure.
