P1391 Glow Plug Circuit Low Input (Bank #1)

• DTC P1391 or P1393 will set when the monitor indicates that all four glow plugs are not being powered on that bank. An open in the glow plug circuits, glow plug relay, glow plugs or monitoring circuit could be the possible causes.
  
  Both DTCs P1391 and P1393 together will set when the monitor indicates that all eight glow plugs are not being powered. An open in all glow plug circuits, the glow plug relay, glow plugs, fusible links or all three monitoring circuits could be the possible causes.
• Possible causes:
  • glow plug relay
  • glow plug shunt
  • open in glow plug circuit(s) or monitoring circuit(s)
  • glow plugs
  • PCM

if its 4 cylinder engine then it four plugs

right renew the glow plug timer/relay if you put a meter on the glow plugs when cold and turn ign on (with help) it should supply power for a about 20 secs ,time depends on outside air temperature ,if all else fails then do a colin --- use a push button switch,wired to a relay so glow plugs can be operated by pushing the switch which you will mount on the dash ,cant beat a manual overide system

So the only thing now is the light staying on ??
Disconect the possative cable on th battery..
That should re-set everything..

You need a hand scaner/reset to reset the lites on this model. You can buy them on ebay or goto your local part store. Removing the lite is also handy

The garage should be able to test the glow plugs without removing them. All the need to do is use an ammeter or amp clamp and measure the current drawn by the glow plugs. the glow plugs should draw 16 - 20 amps each. much less than that and they want replacing.
