what is this relay ??

[triton]

can someone please tell me what the little relay is behind the GPR in the pic ? This is a E-350 7.3L

Just wondering since this is a van and a pain in the a$$ to work on, maybe I should replace it while I'm in there ??

Intake air heater

To reduce white smoke during long idle periods at low ambient temperatures, the PCM will activate the intake air heater. Specific conditions must be present before the heater is activated:


ambient temperature must be below 0 °C (32 °F)
Engine Oil Temperature (EOT) must be below 55 °C (131 °F)
Vehicle Power (IVPWR) must be between 11.8 and 15.0 volts
parking brake must be applied on manual transmission vehicles
the transmission must be in Park or Neutral on automatic transmission vehicles
glow plugs must be off

thanks ! Do you think it's wise to replace it being that it's 9 yrs old and I do see temps well below 32 in the winter ?

I've never seen one go bad. The gpr's do fail on occasion.

ok, I'll leave it then. Vans are just such a pain to work on I figured while in there, maybe I should replace it too. The GPR has been giving me trouble for a while. thanks for the help.
