Outstanding information. I’m testing the front impact sensor on my 2008 F150 that Ford graciously decided to discontinue with no alternative options. My clock spring is good and nothing else seems to be malfunctioning. So the impact sensor is the next most likely suspect. But I was unsure what to look for when testing it with my multimeter. Thank you for this information!
@@alley55customs93 I would be grateful if you could show the test of side crash sensor from Renault Clio 2 1.5 dCi 2002 because I searched everywhere and no one had done this.
When he says zero resistance he means OL. This means it has infinite resistance, or basically it means that the circuit has opened. A sensor that reads OL will no longer complete the loop for the srs circuit to be completed.
Hi! Is there a way to check for short to ground from the sensor back... Car is a 06 Hyundai Tucson.scanner states B1326 front impact sensor short ro ground.. //Fredde
I had a faulty sensor and when I tested it against the new one, the resistance was lower, but it wasn't an open circuit, what's going on there? When I put the new one in it's place the dash light went off and it was all fine.
These go bad on their own. I’m pretty sure most of them reset after a collision. Someone ran into the front of our Ford Ranger one year and set off the airbags. The sensor was not replaced as I recall. Just some moderate body work and new bumper. If the unit is physically damaged due to the collision, then yes.
This is garbage. Impact sensors from different car manufacturers can have very different internal designs. Some have mechanical triggers inside where this resistance testing may work. Others use internal accelerometers in which case resistance testing doesnt work. There may be other types of internal designs where resistance testing may or may not work. It's ignorant to suggest this resistance testing can be used universally on all impact sensors.

these are the crash sensors in the front grill area?
Thank you so much for this short but good explained video.
I’m glad I could help you out. Let me know if you need assistance on another vehicle.

Haha He should have said continuity on the first sensor
Continuity and resistance coexist by definition.The 16k resistance is continuity.
can this be done on the wiring from car without having to remove the sensor ?
nice! looks exactly as Tesla Model 3/Y sensor. Thank you Sir! Best regards from Ukraine Odesa

Hi, you think 1000 ohm its ok on 2002 tahoe? Front impact sensor

Did it just go bad or was it after a collision?
