The tire pressure light won't go off....

Have you checked the brake fluid in the master cylinder?

fixya, hybrid fixes.. wow......
double posted too,,,, back up one.

wendy dont fiddle about in any hybrid, there is High voltage there
lethal as H3LL. nor with Air bags, Read the FSM. first.
and post engine RPM at low oil pressure, and dont drive it.

Error Code: P0A7F/78.
Description: Battery module deterioration.
Solution:
-Check for poor connections or loose terminals at the battery
module, the battery current sensor, and the BCM module.

Typically what happens is that one or more of the tire pressure sensors has gone bad in your valve stems.

Try to do your inflations when the tires are as close to cold as possible, ie: at the closest practical gas station. The further you've driven the more they will warm up. The tire pressure spec. on the sticker in door well is cold pressure. In a pinch when putting in air after driving a "fair" distance, go 2~4 lbs. over, and then recheck when cold.

Also, how good is your gauge? Are you using your own, or the gas station's, or just that funky thing on the pump hose?

Also, consider bumping them up, say to around 40 lbs (verify the max pressure indicated on the sidewall is still higher, likely 44). This will be more likely to rule out measurement inaccuracies, and improve your mileage as well. The only downside is a harsher ride.

Please check for the following conditions:
* Low tire pressures. Raise the tire pressure to a "recommended" setting, preferably close to or at the tire's maximal pressure rating.
* Perform a four wheel alignment and look for signs of unusual tire wear.
* Add additional insulation to the rear passenger and cargo area of the vehicle.
* Check for a defect in the rear control arms as identified in service bulletin 08-001 affecting primarily 2006 and 2007 models. This defect is responsible for abnormal tire wear, noisy operation and even responsible for poor directional tracking at highway speeds.


Keep us updated; hope helps.

Tire Pressure Monitor System

What was the pressure.? the tire pressure specification should be on the drivers door jamb. It needs to be set cold. The light will go off when each tire signals that it has the proper pressure.

If you set all of your tires to the amount specified on the sticker in the drivers door jamb, it should go out itself. If it doesn't, you might have a bad tire pressure sensor. (There is one per wheel)

yes,

the best overall pressure is 32-34 cold tire inflation, better tire wear and a slight increase in MPG
