96 Ford Aerostar P0340 Code: Common Causes and Solutions for Cam Position Sensor Failure

Model: 96 Ford Areostar Fault Code: P0340 Posted: 2008-04-06 14:25

I'm experiencing a P0340 diagnostic trouble code on my 1996 Ford Aerostar, which points to a cam position sensor issue. I've already performed a visual inspection of the sensor and it appears intact. However, I'm wondering if there are any known common problems or failure patterns specific to this model year and vehicle type. Does anyone have experience with recurring issues related to the cam position sensor on 1996 Ford Aerostars? Are there typical signs of failure beyond just a visual inspection?

If the physical appearance of the sensor looks good, it's less likely to be a faulty component—though other factors like wiring or connector corrosion could still play a role.

Jeff, I'm specifically asking if there are any commonly reported failure patterns for the cam position sensor in 1996 Ford Aerostars—such as frequent sensor degradation or environmental-related issues. I've already reviewed the main page of that site.

Given that this is a 12-year-old van, mechanical wear is plausible. However, I don't know of any dominant failure pattern beyond general sensor degradation—checking for a Technical Service Bulletin (TSB) might provide more targeted insights.
