хз, решил ли топикстартер вопрос, но часть инфы заброшу в эту тему.
как-то после покупки своего рэма (б.у., 86к пробега) поймал 0524-ю ошибку. вылазила с завидным постоянством и пропадал сама супстя какое-то время.
нарыл в инете инфу, в. т.ч. TSB (оф доки с найденными ошибками).
кратко: в части случаем надо перешивать мозги, в части случаев проблема с маслом и некоторыми узлами, о которых уже писали в теме (egr клапан)
в моем случае решилось промойкой двигателя и свежим маслом 5w20 mobil1, привезенного из США
А вот выдержки из инета:

Module (PCM) with new software.

NUMBER: 18-003-08
GROUP: Vehicle Performance
DATE: January 19, 2008
NOTE: This bulletin applies to the above listed vehicles equipped with a 5.7L engine
with MDS (sales code EZB) built before the following dates:
• (HB/HG) built before August 15, 2007 (MDH 0814XX)
• (LX) built before September 14, 2007 (MDH 0914XX)
• (DR) built before August 16, 2007 (MDH 0816XX)
• **(WK/WH/XK/XH) built before January 8, 2008 (MDH 0108XX)**
SYMPTOM/CONDITION:
The vehicle operator may experience a Malfunction Indicator Lamp (MIL) illumination due
to the following Diagnostic Trouble Code (DTC):
• P0524 - Engine Oil Pressure Too Low
DIAGNOSIS:
Using a Scan Tool (StarSCAN®) with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all engine systems are functioning as designed. If other DTC's are
present record them on the repair order and repair as necessary before proceeding further
with this bulletin.

Diagnostic Trouble Code (DTC) P0524 has a generic description of "Oil Pressure Too Low."
There are SEVERAL things to consider here:
First: Your engine is VERY sensitive to oil viscosity. Since it came up right after an oil change, I would question whether the correct viscosity oil was used. Also, if there has been any aftermarket fluids/chemicals added to the engine oil (like those that make claims to clean your crank case) this can have an adverse affect on oil viscosity.
Second, The actual oil pressure should be checked with a manual gauge to verify proper oil pressure sending unit operation and to see if a low oil pressure condition actually exists.
Finally, If everything is OK in the items listed above, there is a Technical Service Bulletin (TSB) published for your truck that has to do with "false" code P0542. It requires an update of your computer software to correct it. The TSB Number is 18-003-08.
If your truck requires the software update, it can be done at the dealership for free if your vehicle is still covered under the 8-year/80,000 mile emissions warranty. (It should be covered unless you have more than 80,000 miles)

In both cases, there is a software update available for this condition. It involves having the dealer connector their StarScan tool to your truck and reprogramming the PCM.
DTC P0406 - EGR Sensor "A" circuit "High"
There is updated software available for your PCM that will correct this code if your vehicle was built prior to mid February 07. If it was built after that, then the EGR valve will need replacing (this is not unusual). Keep in mind that could be time for a new valve, but you dont will need to change the tube, but new gaskets are a good idea.
DTC P0524 - Oil Pressure Too Low Oil pressure sending unit (sensor) voltage input above the maximum acceptaple voltage.
If the software is up to date, then have the oil pressure sensing unit must be replaced.
Additionally, check this TSB SUPERSEDES TECHNICAL SERVICE BULLETIN 18-044-07, DATED OCTOBER 12, 2007, WHICH SHOULD BE REMOVED FROM YOUR FILES. ALL
REVISIONS ARE HIGHLIGHTED WITH **ASTERISKS** AND INCLUDE THE ADDITION OF YEARS, MODELS AND CLEAN DATES.
THE StarSCAN FLASH FILES FOR THIS BULLETIN MUST BE RETRIEVED FROM THE INTERNET.
StarSCAN SOFTWARE LEVEL MUST BE AT RELEASE 8.04 OR HIGHER FOR THIS BULLETIN.
StarMOBILE STANDALONE MODE OR StarMOBILE DESKTOP CLIENT MAY ALSO BE USED TO PERFORM THIS PROCEDURE.
