![]() ![]() I should add, there are no codes present and never been while I've had the car for these sensors. I can only assume that the solar sensors are faulty, because their voltages do not change with a change in light conditions. When I unplugged them, I checked resistance at both sensors – both were showing almost identical figures, about 3.4 Ohms (I think, because I am not the world's best electrical diagnostician when the multimeter was set at '20' Ohms, this reading was the result). When I unplugged one of the sensors, the Tech 2 showed that sensor's voltage at 5.00v. I did wait perhaps 30-40 seconds when going from dark to light to see if the sensors were slow to respond, but even then there was no change. The voltages do not change at the sensors, according to the Tech 2, with changes in light as described above. In my driveway in daylight, I tried firstly covering the sensors with a black cloth and then removing it, and shining a bright LED work light directly at the sensors (one at a time). I have a Tech 2 scanner and it shows a voltage of about 4.6v for both solar sensors.įrom what I understand, the solar sensor voltage should change according to light conditions. ![]() In chasing down a problem I have with a passenger side air door, (see this thread here I have discovered that the solar sensors might be faulty. ![]() I'm wondering if you guys know much about the solar sensors (or sun load sensors, ALLDATAdiy uses both terms to describe these). ![]()
