Chrysler Repair: 2.5 V-6 oil pressure sender/switch location, oil pressure sender, oil sending unit

Question
V-6 OIL SENDING UNIT LOCATION...../ ALSO,ANY HISTORICAL PROBLEMS WITH THE OIL LIGHT STAYING ON , AT COLD START OR HIGHER REVS THE LIGHT GOES OUT....NEVER ANY TICKING OR KNOCKING NOISE

Answer
Hi Steve,
The oil pressure sender switch is located on the back side of the engine, below the exhaust manifold port for the #1 cylinder.
This light question is fairly common with all makes/models. If your idle rpm is a little on the low side which means the pressure is going to be low enough to turn on the light after the engine warms the oil, which also lowers the pressure a bit. The actual minimim oil pressure is 5 psi so if you wanted to check this out you could have it measured with a gauge at a shop or buy a gauge and substitute it for the oil pressure light sensor. But in my experience I would not be concerned for the moment, but rather the next time you change the oil increase the 'weight' by one step*, which increases the viscosity and thus will raise the pressure at idle so that the light will usually not come on anymore. Another approach would be to buy a new sensor for the light and replace the present one which may be off-value. Either of those approaches don't have any labor charges if you do it yourself.
The only time you really have to be concerned is if the light comes 'on' when you are driving and the rpm is higher than about 1,000 rpm as that could mean there is insufficient oil reaching all the moving parts.

*If you have been using 5W-20 try instead 10W-30 for example.
PS Sorry for the delay, Your question just came to my attention in the 'pool'.
