Tire Pressure Sensors

Anyone know at what psi the tire pressure sensors activate the low psi warning?

Re: Tire Pressure Sensors

According to my Technical Manual for the 2004.5, it's at 28 psi. It will light up and make an audio warning. If just the light comes on with no warning, then it is indicating a systems error.

Re: Tire Pressure Sensors

I thought our system ran off the abs and just sensed a difference from the other three. Meaning all 4 could be below 28 and it wouldn't go off.

Wonder what the pressure is for the 6mt is?

I really need to download that thing...

Re: Tire Pressure Sensors

DED,
I heard the same thing but this is cut and pasted straight out of the manual. It's for a 2004.5 Coupe. Doesn't specify AT or MT.

"System Description
TRANSMITTER
A sensor-transmitter integrated with a valve is installed on a wheel, and transmits a detected air pressure signal in the form of a radio wave.

REMOTE KEYLESS ENTRY RECEIVER
The remote keyless entry receiver receives the air pressure signal transmitted by the transmitter in each wheel.

BCM (BODY CONTROL MODULE)
The BCM reads the air pressure signal received by the remote keyless entry receiver, and controls the low tire pressure warning lamp and the buzzer operations as shown below. It also has a judgement function to detect a system malfunction.

LOW TIRE PRESSURE WARNING LAMP
The combination meter receives tire pressure status from the BCM using CAN communication. When a low tire pressure condition is sensed by the BCM, the combination meter low tire pressure warning lamp and buzzer are actives.

Condition Warning lamp Buzzer
Less than 200 kPa (2.0 kg/cm2 , 28 psi)
[Flat tire]
ON Sounds for 10 sec.

System malfunction '(Light)' ON '(audible warning)' OFF"
