Thread: 06 gp False Hood ajar

If I remember correctly the hood switch on the grand prix is not a simple open and closed switch...It has resisters inside and depending weather it it latched or unlatched a switch inside switches different resistance.

All what would have to be done to bypass it is to get a resister equal to what the switches resistence would normally be when closed.

I will look for the resister value tonight and post back, I remember seeing it in my car service program when I was going to add oem remote start to an 04.

Checked on the resistance for the switch when closed.

It is between 700-800 Ohms. If you can find a resister or combination of resisters to give you a resistance value within those numbers and hook them to the plug that goes to the hood latch it shouls start if this is the problem.

Dont cut your hood latch connector though, the ends of the resister will just slide into where the pins are on the connector. This should test weather the latch is bad or not.

Thank you! I will try it out! Hopefully it works. I appreciate the information. now where to get 800 ohm resister.........

and will this work? (i found it on ebay)

IRC
Resistor 800 Ohm 10W 10%

Measures:

• 1-7/8" long
• 3/8" High
• .3/8" Wide

I just need to know if watts dont matter not sure what the % is for either. thanks!

Just went through this with an 07 Grand Prix. The 700-800 Ohms reading is when the hood is closed. After poking and prodding and testing found out there was a chafed wire going to the sensor on the harness side that was broken. What happens is it rubs on the edge of a plastic, or fiberglass, piece behind the grill and allows the wire to corrode to the point it looses connection. Repaired the fault and works like a charm.

An addition to this is that the closed position of the sensor was giving me a Ohm reading around 6.5k.
