Aug 30, 2021 Brand new 2021 Pacifica with just 1000 miles has a check engine light on. Took it to the dealer, shows camshaft position sensor error. Cannot get it looked at till some time next week. Dealer stated that it was safe to drive. On the way home the stop start system disabled and the A! error light is on. The engine sounds louder during acceleration.
Concerned if driving the van will cause further damage to the engine. 2018 Chrysler Pacifica Touring L Joined

The description you provided is a bit vague as there are numerous codes that fit that description, but have different meanings. As long as the check engine light isn't blinking, you're probably not causing any additional damage. I still wouldn't drive the vehicle any further than necessary.

The code was PO390-status pending. Also noticed on the sheet the dealer gave me that there is a stored error above the PO390 which is PO6DD. The dealer never mentioned this or said anything about it.

Also noticed on the sheet the dealer gave me that there is a stored error above the PO390 which is PO6DD. The dealer never mentioned this or said anything about it. The PO390 code is a camshaft position sensor fault for the exhaust bank. I would leave the oil pressure info up on the center cluster to make sure your oil pressure isn't too low or too high. Too low will cause damage. Too high should have a relief valve that releases excess pressure.
The PO6DD comes back as this from a Google search. "
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 fromlow 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."

The PO390 code is a camshaft position sensor fault for the exhaust bank. I would leave the oil pressure info up
on the center cluster to make sure your oil pressure isn't too low or too high. Too low will cause damage. Too high should have a relief valve that releases excess pressure. P0390 indicates a fault with the bank 2 (front/left cylinder head) intake camshaft. I've attached an excerpt from the service manual below. P06DD is defined in the
service manual as "engine oil pressure control circuit stuck OFF." I suspect the observed oil pressure will be high (65+ PSI) at all times due to this fault. The oil pump operates in high pressure mode when the solenoid is OFF, and low pressure mode when the solenoid is ON. During normal operation, low pressure mode (about 29 PSI, solenoid on) is used from idle to around 3,000 RPM. The PCM enables high pressure mode (about 65 PSI, solenoid off) between 3,000-4,000. Exactly when high
pressure mode is enabled depends on a few variables like operating conditions, oil & coolant temps, and speed & load. The service manual is more descriptive, but that's basically what it says in fewer words. Unfortunately, my service information source is all pictures, so I don't have the ability to copy and paste exactly what it says. Before jumping to conclusions, check your oil level with the engine warm about 5-10 minutes after shutting it off and add oil as necessary. The
dealership should have done this when you took it there to get it looked at the first time, but I'd still check it again anyways. A shotgun internet diagnosis is that you probably need a new engine oil pressure control solenoid. AFAIK Mopar doesn't sell this part separately and only includes it with a new oil pump. Realistically, more hands-on troubleshooting is definitely necessary to confirm this.
