Obd Codes And Possible Remedy

[Stagecoach]

Hi all. Driving yesterday and my EMU light came on and "Engine fault" appeared in the display.

 

I read the codes and cleared them, but they came back, without the emu light.

 

The codes where:

P0102 Mass or Volume Air Flow Circuit Low Input 

 

P0341 Camshaft Position Sensor Circuit Range/Performance 

 

P1352 Ignition Coil A Primary Circuit Malfunction 

 

Are they linked, suggestions for a fix please.

 

Citroen Xsara Picasso 2004 2.0 HDi.

 

Thanks in anticipation.

Check battery voltage and earths.

 

Have you considered a BSI reset?

 

Check connector to MAF and Crank position sensor; unplug, check for corrosion, replug.

P1352 might be a glow plug problem.

P0341 may be a faulty cam shaft sensor.

P0102 may be the air flow sensor (MAF) is faulty and it may be this is the one that put the EML on with the others already being there but not affecting the running.
