2015 Impala Limited Tire Pressure Monitor False read
This is a 2nd question with a few more specifics.....Having difficulty with my
2015 Impala Limited (old style) LTZ with a bad left rear wheel speed sensor
At 91,000 miles
Sensor says I am at 23# & manual air gages 2 different ones say it is at at
Need advise on what some of the likely fixes are
On Aug 13th Driver Info Ctr read said it was at 27# & now 2 weeks later it
reads 23# so the signal is weaker and tire pressure is same 34#.
We had a 2 day rainy period before today when the low air pressure warning
light came on.
Wondering if the connector is shorting or is corroded??.
May take tire off and see if I can disconnect clean lube(w electric-cleaner) &
Anyone have better ideas Thx
Battery in that sensor is dying, or the sensor is going out. Either way, you have to remove the tire to get to it, so, I'd wait until you need new tires.
Thx now understand Tire monitor is inside tire requiring dis/re-mounting and is different from wheel speed sensor issues
Was getting message on DIC it was LR tire down. It was the RF tire that was at 31# vs 35 recommended Prior Service Shop tech who did tire rotation failed to to update tire sensor by wheel location
