Infiniti replaced 2 of the TPMS sensors / tyre valves on my

Resolved Question:

Infiniti replaced 2 of the TPMS sensors / tyre valves on my FX37 & now the dash warning light has come on. Infiniti has had 2 goes at fixing the problem saying they have re-programmed the sensors on both occasions, but the problem persists. If I select the 'Info' button and then select tyre pressures, the 2 replaced sensors on the graphic do not show a tyre pressure.When I set off from cold, the dash warning light flashes for a while then just stays on.Any ideas on a solution please?

Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

First make sure they did not leave the old sensors that were removed in the vehicle somewhere.I have seen this done before and it confuses the computer and causes this issue.

If this is o.k. and the only sensors in the vehicle are the ones in the wheels/tires and you have no readings at all the dealer or a repair shop needs to use their tire pressure test tool to see if the new sensors are still sending out a signal.If they are not then the sensors they installed are faulty and need replaced again under parts warranty at no charge to you.

If the sensors are sending out a signal then the tire pressure low pressure module is most likely faulty needing replaced.It is located under the dash on the passenger side.It can fail internally and causes a fault like this here with it needing replaced.You would need to have this tested further to see if for sure it needs replaced but I have had to replace it before for this type of fault here.

Pete,
Can you describe the Tyre Pressure Low Pressure Module and exactly where it is in the car in case I take my car to another dealer to get it fixed? Any idea of the price ?Also, would a garage other than Infiniti have a Tyre Pressure Test Tool or is this something just for the TPMS systems on Infiniti cars?
Expert:  Peter Zavarelli replied 1 month ago.

The tire pressure module is what monitors the tire pressures.If a tire becomes low then the module turns on the warning light/message you see on the dash.I show a cost of around $500 for this module and a half hour labor to have replaced.

Any shop or garage that has a tire pressure test tool can usually test this for you and replace if needed.Below are the only images I show on its location.
