RF TPMS receiver
Where is the location of the receiver for the rear tire TPMS sensors? The front tires read correctly, but the rears read 27-28 lbs continuously no matter what actual tire pressure is....

Are the sensors correctly matched to the tire/wheel locations? Procedure is in your owner's manual, page 5-65. http://www.vadengmpp.com/owners-manu...vrolet-HHR.pdf

A 2008 has the RCDLR under the headliner bump next to the rear view mirror. That would not be the cause of one wheel displaying the wrong data.
2008s may not have the ability to relearn the positions with the Owner Manual method due to a firmware problem. They do not relearn by themselves, as many tire jockeys will try to convince you. When the tires are replaced or rotated they must be relearned.
So, if nobody ever relearned them there is a good possibility that the REAR tires are fine and the FRONT tires are under inflated.

Here's a TSB
#08-03-16-001B: Key Fobs Inoperative, TPM System Not Reading Correctly - Dashes on Al Four Tire Readings, DTCs C0775, C0569, B3105 Set, Unable to Program TPM Sensors (Reprogram RCDLR) - (Jul 31, 2008)
Subject: Key Fobs Inoperative, TPM System Not Reading Correctly - Dashes On All Four Tire Readings, DTCs C0775, C0569, B3105 Set, Unable to Program TPM Sensors (Reprogram RCDLR)
Models: 2008 Chevrolet Cobalt, HHR, Malibu
2008 Pontiac G5, G6, Solstice
2008 Saturn AURA, SKY
--------------------------------------------------------------------------------
This bulletin is being revised to update the Important statement to reflect the new direction to no longer contact TCSC. Please discard Corporate Bulletin Number 08-03-16-001A (Section 03 - Suspension).
--------------------------------------------------------------------------------
Condition
Some customers may comment that the key fobs are inoperative or that the TPM system is showing dashes as the reading for all four tires.
Technicians may find DTCs C0775, C0569 and B3105 set simultaneously in the RCDLR module.
In addition, the technicians may find Tire Pressure Monitoring sensors are unable to be programmed to the vehicle by adding or releasing pressure to the tire while the vehicles in the TPM learn mode.
Cause
These conditions may be caused by the following:
• The RCDLR may lose its transmitter and tire pressure monitoring data from its memory if a low voltage condition occurs on the vehicle.
• The ability for TPM learning by adding or releasing pressure to the tire has been disabled in the RCDLR.
Correction
Reprogram the RCDLR with an updated software calibration to address both issues listed above. This new service calibration is available on TIS2WEB using Service Programming System (SPS). As always, make sure your Tech 2® is updated with the latest software.
Important: If the Tech 2® could not establish communication with the RCDLR AND the programming event ended with error, attempt to reprogram in Service Programming System (SPS) by selecting "Remote Control Door Lock Receiver (TSB 08-03-16-001) with E4399 error -- Pass Thru Only".
Once the RCDLR module has been reflashed with the latest software and calibrations, the following may also be necessary:
• Relearn all keyless entry transmitters.
• Reconfigure the tire pressure placards and the tire type.
• Relearn the tire pressure sensors.
Refer to SI for the procedures to relearn transmitters, placard and tire type configuration and tire pressure sensor learn.

Our 2008 2LT has the re learn TPS option in the setting menu, I have used it before. Just set it up to learn and it will blink at the corner to adjust pressure, then honk horn and you follow the blinking lights in same manner.

Really? The Owner Manual for 2008 only has the press "LOCK" & "UNLOCK" at the same time. I wish that my 2008 LT had the option in the settings.
