Hello all. I just bought a 2012 Dodge Grand Caravan which I was very excited about until I drove it off the lot. Within three miles of leaving the dealership, the MIL came on steady and would not go out. All signs are pointing towards code P06DA. I am taking the van back to the dealer for the third time on Monday to further troubleshoot – and hopefully rectify - the problem, but I was hoping someone on the forums, who knows more about auto repair could shed a little more light on what this code refers to for Grand Caravan and how serious the problem might be. All I have found to date is that the code may refer to either of the items listed below. Can anyone shed some light on what I am dealing with? Many thanks.


ENGINE OIL PRESSURE CONTROL CIRCUIT / OPEN
Or
P06DA-DUAL STAGE OIL PUMP CIRCUIT

 

The van is back at the dealer today. I will post any new info to the board as I receive it. Thanks

 

hello all, got a problem. wife noticed engine light come on our 2012 dodge charger sxt. had it diagnosed and code p06da came up. engine oil pressure control circuit open. a switch or relay i was told by autozone code reader guy. any suggestions. autozone guy could not reset code, he said only a technician can legally. any ideas? wondered what was found out with the van

 

this is off another site jeep forum a person by Andrea Social Care specialist
FIAT Chrysler Automobiles posted on this code....


This is what I found for
P06DD-DUAL STAGE OIL PUMP STUCK LOW in the service manual:


Theory of Operation
The engine oil pump features seven vanes and a moving element that continuously adjusts to maintain a regulated oil pressure supply by varying the displacement of the pump. The pump has two regulated pressure stages of operation controlled by an on/off solenoid. Low pressure mode regulation (solenoid on) is approximately 200 kPa (29 psi) and high pressure mode regulation (solenoid off) is approximately 450 kPa (65 psi). The Powertrain Control Module (PCM) switches the pump between stages based on engine operating conditions, oil and coolant temperatures, speed and load. Under most typical conditions, the pump will run in low mode from idle up to around 3000 rpm and switch from low to high mode between 3000 and 4000 rpm. The maximum oil pressure in the engine is limited to 1000 kPa (145 psi) by the relief valve. Pressure in the main oil gallery of the engine can be monitored with diagnostic equipment through the oil pressure sensor mounted on the rear of the oil filter module. The minimum pressure for the engine is 41 kPa (6 psi) at any operating condition. Anything under this pressure could result in damage to critical moving parts.

When Monitored:
Based upon Engine oil temperature, the monitor runs when engine speed (RPM) is over a calibrated value. The cooler the engine oil, the lower is the enable engine speed (Minimum 1000rpm). To evaluate the dual stage oil pump, fully warm up the engine. To run DUAL STAGE OIL PUMP STUCK LOW (P06DD), drive vehicle with engine speed over 3500 rpm.

Set Condition:
The Powertrain Control Module (PCM) senses the oil pressure is less than a low threshold for 5 seconds. One Trip fault.


Possible Causes
ENGINE MECHANICAL FAILURE
ENGINE OIL PRESSURE SENSOR
DUAL STAGE OIL PUMP
Additional, related info for the code P06DD (from TechCONNECT):

Vehicles have been showing up at Dealers with engine runs rough and/or Diagnostic Trouble Code P06DD set. Dealers during normal diagnosis could also identify that the oil pressure is low.
Beside the normal diagnostic procedure possible causes the two items below should be verified:
1. One cause of this has been determined to be that the wrong oil filter has been installed after an oil change by an independent repair facility or the Customer that has
purchased the oil filter in the aftermarket. These filters may be too short or even slightly too wide .
If this is present, first verify that the correct Mopar oil filter has been installed. This can be done by verifying the part number on the filter or that the filter has the Mopar
symbol on it. If the incorrect filter is installed correct this condition and inform the customer that they should return to the point of purchase for a refund.
The correct Mopar part number is 68079744AB.
. 2. The second cause has been determined to be a cut or slit in the O-ring at the top of the pick-up tube on the oil pump. A bore scope can be used to view the top of the pick-up tube to see if the O-ring is not seated all the way around the tube. The O-ring is blue in color and it should not be visible if installed properly

Symptom/Vehicle Issue:
MIL Illuminated Or U-Codes or C-Code Active/Stored Due To Harness Rub Through
Diagnosis:
Verify vehicle complaint and perform diagnostics for the DTC. There is potential for the wiring harness to rub on the A/C hose. The codes that may be stored or active are; P1618, C2204, U1404, U1400, P0018, P0345, P0349, P0019, P0390, P0394, P0298, P1239, P0196, P0197, P0198, P0520, P0521, P0523, P1524, P0340, P0365, P0108, P0107, P0111, P0112, P0113, P0116, P0118, P0128, P0129, P2181, P0344, P0365, P0369, P0652, P0653, P0107, P0108, P0315, P0335, P0336, P0339, P0300, P0301, P0302, P0303, P0304, P0305, P0306, P000A, P06DA, P06DD, P2181, P0117, P0116
If the condition is intermittent, or the diagnostics were inconclusive, perform the below repair procedure.
Repair Procedure:
1. Inspect wiring harness.
2. If wiring harness is damaged repair as necessary.
Verification:
Start vehicle and run to operating temperature. Road test to verify that the DTC does not return.

 

what I got from this posts too is theres a blue oring and maybe oil pump needed too replacement. http://www.jeepforum.com/forum/f96/c...78/index4.html

 

[QUOTE=mreeve1128;2823946]Hello all. I just bought a 2012 Dodge Grand Caravan which I was very excited about until I drove it off the lot.

All I have

 

First think to check is, Do you have the correct oil filter. If you have the correct filter. Then it most likely the duel stage oil pump.

 

Code P06DA Engine Oil Pressure Control - Circuit Open.

This could be caused by a bad oil pressure sensor.

 

Yes it could be a bad sensor. But the only way to replace the sensor is to replace the duel stage pump.

 

On the 3.6L Pentastart the engine oil presssure sending unit is on the back side of the oil filter/ cooler unit. It's not easily accessible but there's kits available that uses modified oil filter caps to check engine oil pressure on the 3.6L Pentastar V-6 shown by the MotorCity Mechanic. I think what you're referring to is the electrical solenoid in the dual stage oil pump that change it from low to high the dealer should be able to command the pump from high to low with their scan tool.
