Engine management light issue

Hello, I'm Danny.

The first thing I would do is perform a CAN scan. It will check all the systems on your car and possible codes it may have stored for these issues you are having. Here is a tutorial showing what is involved with a CAN scan:

Once you have this performed get back to us with any code information that was stored in your vehicle's computer and we can then properly diagnose. After that we can also provide you with diagnostics steps. Hope this helps and thanks for using 2CarPros.

Hi,

I noted we haven't heard from you for a couple days. I was wondering if any progress has been made or if you needed additional help. If possible, let us know. We are interested in knowing.

Take care,
Joe

Hello again.

I've attached some descriptions on the code information you provided.

P242F Description The Powertrain Control Module (PCM) monitors the pressure decrease at the diesel particulate filter following a diesel particulate filter regeneration for a concern. The PCM calculates the amount of ash and the pressure increase the ash generates in the diesel particulate filter. During a regeneration the PCM expects the pressure to decrease. The amount of pressure decrease expected by the PCM is based on the temperature and flow of the exhaust gas. The test fails when the pressure reading at the diesel particulate filter pressure sensor does not decrease by the amount determined by the PCM.

P242F Possible Causes What does this mean? Diesel particulate filter is full of ash Damaged diesel particulate filter pressure sensor Faulty Exhaust Gas Temperature (EGT) Exhaust Gas Temperature (EGT) harness is open or shorted Exhaust Gas Temperature (EGT) circuit poor electrical connection Faulty Mass Air Flow (MAF) / Intake Air Temperature (IAT) Sensor

The P0380 trouble code notes an issue with the glow plug heater circuit A.

What the P0380 code means
The P0380 code is a standard OBD-II trouble code suggesting an issue within the glow plug heater circuit. When the powertrain control module (PCM) detects a variation in the voltage from the “A” area of the glow plug heater circuit that is more than a 10 percent variation from the expected output, the P0380 code will be detected. This code is associated with numerous other glow plug trouble codes.

What causes the P0380 code?
Many things can trigger the P0380 code. Some of the more common issues include:

Malfunctioning glow plug or relay
Faulty glow plug timer
Faulty glow plug module
Blown fuse in the circuit
Faulty wiring and electrical connectors, such as corroded connectors or open

What the P0191 code means
The power control module (PCM) regulates the amount of fuel that is released into the combustion chambers by controlling the fuel injectors. This process works to reduce tailpipe emissions. In order to work effectively, the power control module must always know what the fuel pressure is. If the fuel rail pressure sensor is giving inconsistent readings, the power control module (PCM) will store the P0191 trouble code.

What causes the P0191 code?
Faulty fuel pressure sensor
Faulty fuel pressure sensor circuit
Faulty fuel pressure sensor connector
Faulty fuel pressure regulator
What are the symptoms of the P0191 code?
Check Engine Light on
Decrease in fuel economy
Engine may be stalling or hesitation
Engine may cut off when the vehicle stops
Unusual smell emitting from the tail pipe
No noticeable symptoms
Trouble codes P0171 and/or P0172 stored in the power control module
What repairs can fix the P0191 code?
Replacing the fuel pump
Replacing the fuel pressure regulator
Repairing any broken, frayed, or shorted wires that lead to the fuel pressure sensor
Repairing corroded connector to the fuel pressure sensor
Replacing fuel pressure sensor
Repairing any vacuum leaks in the engine
