Fuel Rail Pressure Sensor Circuit Range/Performance

VEHICLE STALLED WHEN DRIVEN OR STOPPED AT TRAFFIC LIGHT. ABNORMAL NOISES COMING FROM ENGINE. WHEN ENGINE OIL WAS CHECKED, NO VISIBLE OIL WAS AVAILABLE IN THE DIPSTICK. INSERTED DIPSTICK A COUPLE OF TIMES TO ENSURE CORRECT MEASUREMENT. EXTREMELY LOW OIL LEFT IN VEHICLE. VEHICLE SEEMS TO BE BURNING OIL. DIAGNOSTIC TROUBLE CODES READ BY OBD2 TOOL WERE: P0011,P0191,P228D,P0089 AND P0014. WHEN INVESTIGATING ONLINE, THIS IS A COMMON PROBLEM WITH THE VEHICLE'S ENGINE. THIS SEEMS TO BE A DESIGN FLAW BEING IGNORED BY THE OEM.

On 7 Aug 2022, I lost cruise control, Navigation function (GPS0 and had problems with other elecrical functions on instrument cluster. I took truck to my local ford dealer; they rand Ford diagnostics on truck and it had 3 module errors listed. They cleared the codes and tried to get me to accept the vehicle. Road tested it and there efforts of clearing the codes did not fix any thing. Brought back in shop on 10 Aug 2022. Diagnostics ran again now narrowed it down to APIM failing 3 times in 2 days. Now deallership says they have to order part from California if they have them in stock. This truck only has 22,000 miles on it. Has had multiple failures of equipment for fuel system listing codes…

I experienced an unexpected Loss of Motive Power (LOMP) event. Late afternoon traffic was fast, estimate 75-80 MPH. I attempted to change lanes get to the righthand shoulder and was very nearly involved in a high-speed collision with a semi-petroleum tank truck. He applied his brakes to avoid hitting me and started to jackknife, but regained control and continued. The truck missed by inches. At this point I had NO remaining power and was essentially coasting until I managed to cross the remaining two lanes of traffic to the shoulder emergency lane. I reset the error codes and continued home with no further occurrences. The incident produced the following warning lamps: Electronic Throttle…

WHILE DRIVING IN HEAVY CITY TRAFFIC, MY WARNING LIGHTS CAME ON FOR "REDUCED POWER", 'TRACTION CONTROL" MALFUNCTION, 'STABILITRAC AND ABS LIGHTS CAME ON. POWER REDUCED TO 25MPH. I WAS CLOSE TO THE DEALERSHIP AND WENT THERE RIGHT AWAY. THE SERVICE WRITER TOLD ME I WOULD HAVE TO WAIT AT LEAST 2 TO 4 HRS BEFORE ANYONE COULD LOOK AT. MY MILEAGE WAS 36,432...432 MILES OUT OF BUMPER TO BUMPER WARRANTY...HE TOLD ME THE CHARGES FOR DIAGNOSING WOULD BE $130. I AGREED. THEN HE EXPLAINED THAT THE THE LOW HP FUEL PRESSURE/PURGE SOLENOID WAS STUCK OPEN, DIANOSE CODES WERE PO191 AND PO496, THEY REPLACED A HIGH PRESSRE FUEL PUMP, R&R INTAKE PLENUM TO REPLACE FUEL RAIL PRESSURE SENSOR AND REPLACE A PURGE…

While driving at approximately 65 mph on the I-405 freeway in Irvine, CA during rainy conditions, my 2019 Mercedes-Benz C300 suddenly and completely lost acceleration without warning. At the same moment, a Check Engine Light illuminated on the dash. I was forced to coast across all lanes and stop in the emergency shoulder in a very unsafe area with high-speed traffic passing close by in low visibility rainy conditions. Multiple vehicles nearly struck us, including one that had to emergency brake directly behind my car in the shoulder. I contacted AAA and the vehicle had to be towed because it was not safe or driveable. My girlfriend was also in the car and both of us experienced significant…

As I was driving down road car began to lose power, check engine light came on and car went into limp mode. Car was towed to nearest repair shop where analysis was made. I was advised to take to dealership for repair. Advised that there was a service campaign issued by the manufacturer on GLB class with M260 motors. See attached report. Took car to MB dealer and informed that an update to the ECU was needed but not available at this time. See attached report. Returned home to PA called Mercedes main office Customer service to check warranty and coverage yes it covered once dealer verifies codes. Called NHTSA to report where they verified that the manufacturer had agreed to repair the issue…

The vehicle is experiencing an intermittent, sudden, and life-threatening drop into "limp home mode" while driving, creating an severe speed differential with surrounding traffic.First Incident (50,584 miles): The vehicle entered limp mode. Authorized Mercedes service center scanned the car, confirming Fault Code P019185 (Rail pressure sensor malfunction / signal above permissible limit value). The dealer applied an Engine Control Module software patch under Mercedes TSB LI07.70-P-078047.Second Incident (53,695 miles): Less than 3,000 miles later, the exact same sudden powertrain failure recurred. The vehicle drastically lost propulsion power immediately after exiting a high-speed freeway…

Fuel Rail Pressure Sensor failure (P0191) This issue generated a check engine light and limp home mode to be initiated. I have had the part changed and when it was changed the previous part had a manufacturing date of 2025. After replacing with new certified part the issue happened again less than a month later. I have researched and found out that Mercedes has issued a Campaign (L107.70-P-078047) for this issue but they are saying my VIN does not have a recall or campaign attached to it. My vehicle is presenting with the exact issues this campaign states and the same P0191 code that is mentioned in the campaign. It states that there is a software update needed and a flash done on the…

My Bosch CP4 fuel pump failed causing my engine to stall while turning at a very busy/fast intersection. This can occur at speed without any warning of sudden failure, putting everyone on the road at risk. Fault code P0087 and P0191 were present, along with a flashing glow plug. Following EA No.: EA11-003 I removed the fuel metering valve and observed and documented metal shavings. The failed component is still installed on my vehicle as I will be having it serviced shortly. The fact that this same component has been recalled very recently in many domestic trucks, but not in the 600,000 VW/Audi vehicles it is installed in is concerning. EA No.: EA11-003 Date Opened: 7-Feb-2011 Date Closed…

2013 Equinox Awd - Issue while driving and coming to a stop or low idle car stalls out while waiting to turn in intersection. Very scary car goes into limp mode after about 15 minutes of driving with engine light on. Have taken to dealer ship in 3/31/2022 code p0191 and p0172 vehicle runs rough.
