P0394
Camshaft Position Sensor "B" Circuit Intermittent (Bank 2)
DTC P0394, sometimes indicated as P039400 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the ignition system causing camshaft position sensor "b" circuit intermittent (bank 2).
The camshaft position sensor B is responsible for detecting the position of the camshaft. It sends this information to the engine control unit, which uses it to control the timing of the engine. If this sensor malfunctions, the engine may not run properly. One common symptom of a bad camshaft position sensor B is an engine that misfires.
There are several possible causes of a camshaft position sensor B circuit intermittent error. One common cause is a bad connection or wiring problem. Another common cause is a bad camshaft position sensor B itself.
If you experience this error, the first thing you should do is check the wiring and connections to the sensor. If they look okay, you may need to replace the sensor.

Check engine light on, obd codes P0016, P0390, P0394. Replaced camshaft and crankshaft sensors and problem still persists; limp mode up hills, and oil loss. Per multiple Jeep Wrangler forums, this is a very wide-spread Jeep phenomenon. Dealers do not know how to fix this. Jeep needs to own up to this defect.

Had to buy a new engine! The truck started running rough on the drive home from work on friday, april 6. On saturday morning, april 7, i took it to get gas. After filling my tank, the truck would not start back up. I had to have it towed from the gas station. Towed it to keller Ford, grand rapids, mi. Codes P0011, P0016, P0017, P0019, P0021, P0172, P0175, P0299, P0313, P0365, P0369, P0390, P0394, P0430 and P052C. The technician also performed a power balance test and a compression test, it was determined half the engine had zero compression and the other half had lowered compression. All of these results indicated the truck needed a full engine replacement. $7,650 for the new engine. A vehicle with 80,000 miles and only 5 years old should not need a new engine. A mechanic told us this is a problem and he replaces an engine on these Ford trucks at least a few times a month. We had the engine replaced at sulforce automotive, grandville, mi

Beginning of feb., lost power on freeway. Went from 65 to 40 mph and could not accelerate. Engine and traction lights came on. Exited the fwy and drove to dealer where i was turned away due to high volume. Left my Jeep at the dealer the following day with this issue and to correct campaign #v51 recall. The engine light wasn't lit anymore and dealer couldn't find anything wrong with it so i picked it up. Couple of weeks later, i failed the smog check i need to register my Jeep, and an engine code showed up, P0394. I took it to other places where the same code showed up and was recommended to take it back to the dealer. Going downhill, my father experienced the same while driving my Jeep. Beginning of march, omw to the dealer on the fwy, i lost power again and the engine and traction lights came on. I showed the dashboard to the service advisor, explained the continued problem and the code showing up. I left my Jeep there for several days because they couldn't reproduce the problem and didn't know what was causing it. The code was cleared when i picked it up. The following day, as i was making a right turn into a parking lot, the engine stalled. I used gravity to partly move back down as there was another car driving into the lot. I put it on "park" and i was able to restart the car. No engine light this time. This morning i lost power driving to the first stop on my street (stop on my side only). I had already entered the t-intersection but could not accelerate to turn left. I put it in "park" then back to "drive" and accelerated normally. There were no cars around because of the corona virus, but i would have been hit on the driver's side if a coming vehicle (who has the right-a-way), decided not to slow down.
