Confusion on tire placement with TPMS
Been fighting my TPMS system ever since I got my 06 XK Limited several months ago. I have several threads here discussing the weird stuff it is doing. I finally decided the TPMS sensors are old and decided to install a new TPMS sensor (68078861AB) along with a new tire (needed) and place it in the left rear since that was the position not reporting. However, after plenty of driving to let the system discover the new TPMS sensor as is proper for the 06 XK Limited, I am still not getting any readings from the left rear. HOWEVER, after noting that my left front tire had suddenly gained pressure (from a normal 34 to 39) after installing the new left rear tire, I became suspicious that there was more going on than I realized. I deflated the left rear and the left front reading suddenly dropped down to 34. That tells me that the left front reading I am getting on the dash is actually my left rear tire reading.
I only replaced one TPMS sensor and it was installed into the left rear. The old sensor removed was a very old part number (56053030AC) and was probably a factory install. I am guessing that the remaining TPMS sensors are old also and their reporting is questionable. I suspect that the computer is confused by erratic TPMS reading from the old sensors and unable to determine which sensor is actually in each position. If true, the only fix is to install new TPMS sensors in each wheel (they need new sensors anyway) along with a new set of tires I want.
Has anyone else experienced a tire (on XK Limited) reporting in the wrong position on the dash display? How did you fix it?
