ECM Diagnostic and tpms problem

[lebanesepathy]

hi, i recently got a 2006 se and shortly joined the forum.
It had the tpms and ses lights on.
i tried the ecm diag but it the ses blinks 5-6 times slow, so what could the problem.
Thanks, got great info even before getting the pathy.

Your PF is at the age that the individual tire stem batteries wear down, causing this.
This mandated feature was thanks to Ford Explorer, Firestone, and the recommended tire pressure to get a soft ride some years ago. As a result the tires overheated & blew.
Personally, I monitor my tires closely & run the PSI to 40-45#. I ignore that blinking light. Some place black electrical tape over it. Otherwise buy new tire stems. Your choice.

Thnx for the info.

what kind of tires are you running that you keep them at 40-45psi

It's a nice feature to have working for those that don't check their tire pressure on a regular basis. It's also good to alert you of a tire going flat while you're driving if you should pick up a nail; it might prevent one from destroying the tire by riding the tire too low. I recommend using Dorman TPMS sensors. You can get them for about $40 each and they have a lifetime warranty. Genuine Nissan sensors are twice the price and have a 1 year/12000 mile warranty. An activation tool and scantool are needed to program them, though, and the tires need to be dismounted from the rims in order to install them.

The SES light is likely another issue. You'll need to get the codes pulled.

So I can't just replace the sensors' batteries ?

General Grabber Sidewall states MAX 44#
I do it to maximize MPG and the ride is not too rough. No uneven wear patterns.
Those on the mileage forum always stress the increase of tire pressure, coasting, throwing the trans into N at long lights, etc.
Some on this PF forum didn’t buy a PF for economy, others complain about the mileage.
Personally I need a PF type vehicle and it gets 10-15% better than my former 98 Tahoe doing similar tricks.

It would be nice if you could, but the TPMS sensors have integral batteries that can't be serviced. You need to replace the entire TPMS sensor assy. They generally last about 6 years, give or take. When one fails, the others aren't far behind. Rather than keep replacing one after another and having to go through the programming, it's more practical to replace them as a set in the long run.
