LocationP1456 Fuel Tank Pressure Sensor Circuit Low August 23, 2018 Add Comment P1456 code - The Powertrain Control Module (PCM) detects that the fuel tank pressure sensor (FTP) input voltage is below the minimum acceptable value.Jul 07, 2021 · P018C is an OBD II fault code that stands for “Fuel pressure sensor “B” Circuit Low”. There are a few things that can cause this code like a bad sensor, or high or low fuel pressure. It pops up when the Power Control Module (PCM) receives an erratic signal voltage from the fuel pressure sensor. 2014 F-150 3.5 Ecoboost - Low Fuel Rail Pressure P0087 and P00C6. 2014 F-150 3.5L Ecoboost with 102k miles. The truck has the wrench and reads 1 warning. It runs fine cold but suddenly shuts off at idle or when doing steady speeds, no matter the speed. I have a little OBDII reader hooked up to it.possible causes for p0171 are vacuum leak,low fuel pressure,restricted fuel filter,dirty maf sensor,dirty injectors. April 25, 2013 at 1:04 am #515007 college man Moderator possible causes for p0171 are vacuum leak,low fuel pressure,restricted fuel filter,dirty maf sensor,dirty injectors.DTC Codes P008A Low Pressure Fuel System Pressure- Too Low * Commonly sets when the fuel filters are plugged, the fuel supply pump has failed, or after replacing fuel filters and not bleeding the system correctly. * See Hard Start/No Start above P0087 Fuel Rail Pressure Too Low * See P008AA fault in the fuel injector return system causes the fuel pressure to be lower than expected. This causes fuel from the high-pressure circuit to be leaked back to the low-pressure circuit. A faulty maximum pressure relief valve will also cause this situation. The high-pressure pump should also be tested to ensure it is capable of delivering ...Read fault codes were: 'Fuel delivery pressure not as anticipated' and 'Fuel delivery pressure low'. Sure enough if you maintained a constant 3500rpm with the vehicle stationary, after about 30 seconds the revs began to drop to about 2000rpm and immediately pulled back up to circa 3000rpm, all repeating in a one or two second cycle.After replacing the fuel filter the check engine light would illuminate and a message of "low fuel pressure" would show on the driver information display. Co...Apr 06, 2020 · The low side fuel pressure is more than 300 kPa (43.5 psi). The engine is not running. The DTC runs once for each engine start. Conditions for Setting the DTC P0089 The high pressure fuel pump actuator command is greater than or equal to 240 or less than or equal to 0 . The condition exists for greater than 5 s. P00C6 Car idles rough first thing when you start it. Drives great. Had several codes which am sure were triggered by one, as is the case with BMWs. Cleared all and only one that came back after 6 miles of driving is 29F3: DME: fuel low-pressure sensor, electric. ax86u vs ax92u -fc
