OBD error code P0149 flashing? Tensed on how bad it can affect your vehicle’s health? Well, you might not like to hear it but it can be extremely fatal for your vehicle’s engine health. Though the vehicle will start but the inconsistencies with the fuel pump timing can damage your engine badly. To know more about this problem, read through our following sections.

Learn More About OBD Error Code P0149

Obd error code P0149 indicates that your vehicle’s PCM has detected some defects in the functioning of the fuel pump timing.

 

Powertrain control module makes use of the fuel rail pressure sensor to check what amount of fuel goes into the fuel injectors. In case it detects that the commanded pressure and the actual pressure are both the same, it will set the error code P0149.

 

What causes this problem with the fuel timing?

 

  • Poor fuel pressure sensor
  • Leakage in the fuel delivery system
  • Defective fuel pressure control actuator
  • Faulty fuel timing solenoid
  • Not well aligned timing marks on mechanical sprockets
  • Faulty PCM (Powertrain Control Module)

Easy Diagnosis Of Engine Error OBD Code P0149

If you want to or really wish to diagnose the issues your vehicle is facing, you will need to follow certain instructions. And if you wish to check whether your vehicle is facing obd error code P0149 or not, you will need to follow these simple steps.

 

Considering that this problem can be caused either by mechanical timing or electrical faults, it is a good option to start with electrical faults as it is easier to detect.

 

For a general check make sure that there are no fuel leaks or damaged fuel delivery system parts. In case you find any damaged parts, resort to fix them.

 

Also check the wire harness between the engine control module and fuel timing solenoid for any damage. Make use of a DMM to measure the resistance across the terminals. Make sure that the resistance is between 10 Ω and 20 Ω across the coil and over 10 kΩ to ground. Replace if resistance is not as specified.

 

For a Mechanical Check make sure that all the timing marks are properly aligned. In case not then you might need to resort to replacement or repair for the same.

 

Mechanical Check – It’s highly unlikely that a timing chain may “skip time” or stretch enough to cause a fuel timing problem – a stretched chain would cause a crankshaft-camshaft correlation fault. More likely is a problem during any recent operation that required the removal of the timing chain. Checking time between the crankshaft and fuel pump will require the removal of multiple parts. Make sure that all the timing marks – on the chain, sprockets, engine block, and cylinder head – are lined up perfectly. Repair as necessary.

 

Common Mistakes When Diagnosing The P0149 Code

 

Before proceeding to correct the issue just make sure you actually have that problem. Also, before you undergo any of the fuel delivery system part replacement, just make sure that the part is actually damaged and the problem does not lie somewhere else.
