GreenGoblin06 Posted March 10, 2022 Share Posted March 10, 2022 I have a 2008 chu613 and when the truck suspension airs up the "Air Suspension pressure" gauge in the dash reads 100psi. is this normal? thought it might act as a load pressure gauge but I'm assuming not. I've replaced the pressure sensor/switch on the front left air bag, and nothing changed. if it's just to read the air bag pressure and not for load pressure what are some good options and places to get one, i don't want anything cheap and chincy? thanks Quote Link to comment https://www.bigmacktrucks.com/topic/69353-air-suspension-gauge/ Share on other sites More sharing options...
Joey Mack Posted March 10, 2022 Share Posted March 10, 2022 what are the tank air pressure gauges reading at the same time? jojo Quote Link to comment https://www.bigmacktrucks.com/topic/69353-air-suspension-gauge/#findComment-491500 Share on other sites More sharing options...
Hans Remmers Posted March 10, 2022 Share Posted March 10, 2022 Average on any 4 bag tandem suspension is 60-70psi with legal axle load weight shouldn't be more than 20psi empty. If it just reads 100 all the time something is wrong. A gauge that will read in load weight requires calibration and is no more accurate than learning what the truck weighs based on bag pressure. If the sensor is tied in at a bag fitting then it should be in the right place. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69353-air-suspension-gauge/#findComment-491505 Share on other sites More sharing options...

Joey Mack Posted March 10, 2022 Share Posted March 10, 2022 is there air pressure at the back of the gauge, or is it electric, and there is a sensor back at the right rear air bag? jojo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69353-air-suspension-gauge/#findComment-491584 Share on other sites More sharing options...
GreenGoblin06 Posted March 11, 2022 Author Share Posted March 11, 2022 its electric and this one has the sensor at the front left bag. doesn't matter if there's pressure to it, the gauge pegs out. ordered an new gauge and going to give it a try to see if that fixes it.

GreenGoblin06 Posted March 11, 2022 Author Share Posted March 11, 2022 update: upon further investigation it was a bad connection at the sensor. one of the pins in the 3-pin harness had pushed out and it wasn't making a connection. thank you everyone for all of your help.
