Why is my Powertrain Control Module not working?
Different sensors in the engine send the PCM data about what the engine is doing. The PCM then adjusts the fuel mixture based on this data. If the PCM is not working properly, odds are that the fuel mixture will not be right. The vehicle may be receiving too much fuel or too little.
Is the DTC p2293 fuel pressure regulator designated 2?
The Powertrain control module or Engine control module (PCM/ECM) has determined that the fuel pressure commanded is not within specifications on fuel pressure regulator designated 2, and will set the DTC P2293.
What happens if the DPF sensor is incorrect?
In some cases, incorrect readings can give a misleading representation on DPF state. In most cases, the sensor will stop operating. This will give a ‘check engine’ light and a corresponding code. This usually triggers limp home mode, so you can expect a noticeable loss of power. DPF exhaust pressure sensor is not expensive.
What causes a p2293 fuel pressure sensor to malfunction?
Check Engine Light illuminated (Malfunction Indicator Lamp) Potential causes of a P2293 trouble code may include: Restricted or pinched fuel lines / clogged fuel filter Faulty fuel pressure sensor or electrical wiring Fuel pressure – Fuel pressure can be checked by using a mechanical gauge attached to the fuel rail.
How to check for fuel pressure sensor problem?
Monitor sensor voltage. Verify an active Diagnostic Trouble Code (DTC) for the sensor. If code is inactive, monitor the Parameter Identifier (PID) while wiggling the connector and all wires at suspected location. If the circuit is interrupted, the PID spikes and the DTC goes active. If DTC is active, proceed to the next step. 4.
What kind of fuel pressure sensor does a 2010 MF DT have?
2010 MF DT should have the mechanical pump mounted on the HP oil pump… also should have a primer pump on filter housing 1 and a half inch dia button on side of rock trap is primer… if it’s electric setup… electric pump is in place of rock trap.. Figured out our buses are 2010 model year, built in 2009, with 2007 EPA standards.
What is The P2002 code on a 2013 MB diesel?
Have a 2013 GLK250 diesel with recurring P2002 code. The MB Have a 2013 GLK250 diesel with recurring P2002 code. The MB dealer inspected and said DPF and DPF pressure sensor required replacement. Have removed, cleaned (kiln), and flow tested DPF.
Where do I find the low fuel pressure code?
The only code it throws now is the low fuel pressure. Dont have any max7’s but on the dt’s ive had good luck replacing the fuel pressure regulator down in the filter bowl not sure where thats at on your bus I looked up on I know and told me this. 1. Using EST, open the D_ContinuousMonitor.ssn.
What happens if the engine control module fails?
If the ECM fails completely, it will leave the vehicle without engine management control, and will not start or run as a result. The engine may still crank, but it will not be able to start without the vital inputs from the computer.
What is the bad fuel system control module code?
IF YOU CHECK YOUR VEHICLE WITH A SCAN TOOL, THE MOST COMMON BAD FUEL SYSTEM CONTROL MODULE ERROR CODE IS P069E. (FUEL SYSTEM CONTROL MODULE REQUEST MIL ILLUMINATION) If playback doesn’t begin shortly, try restarting your device.
What is the name of the engine control module?
The engine control module (ECM), also commonly referred to as the engine control unit (ECU) or powertrain control module (PCM), is one of the most important components found on virtually all modern vehicles.
What to do if no power is found at Powertrain Control Module?
IF YOU FIND POWER AT THE POWERTRAIN CONTROL MODULE, LOCATE THE BREAK IN THE WIRE TO REPAIR. IF NO POWER IS FOUND AT THE POWERTRAIN CONTROL MODULE, REPLACE WITH PROGRAMMED UNIT.

What are the symptoms of a bad ECM power relay?
A bad relay may cause the vehicle to crank, but not start, or sometimes not even crank at all. 3. Battery drain or dead battery. A failed ECM power relay can also cause a battery drain or dead battery. If the relay shorts it can leave power on to the computer, even when the vehicle is turned off.
What happens if your PCM is not working?
Running Poorly The PCM is what ultimately controls and regulates your fuel system. In some cases, a PCM problem will cause the vehicle not to run at all. If your PCM is malfunctioning, you can expect to see almost every error light imaginable appear and disappear at some point. The PCM controls your vehicle’s fuel and emissions system.
