Just got back from having the same Cam Sensor problem repaired.
First 4 months ago the first one went. Was replaced with an aftermarket sensor – all good! Now the exact same problem happened again while 3 hrs from home. Limped home. I found out that there are two Cam Sensors. Got #2 replaced and all is well again.
Consider having both replaced if one goes! This will save you much time, money and potentially a dangerous driving situation.
Still happy with the van though. 2004 with only 170,000 kms, body still decent. Enjoy.
