I took my 2006 maxima to deler to get it reflash.I was told this car does not have a reflash. true or false

May or may not be true. The way to isolate them is to use an anti static bag like the one it came in or wrap it in aluminum foil.

False there are many systems that the pcm controls.

Emission Guys are not technicans & give out speculative advice,
so as to keep the line moving

You need a shop to work on the communication issue, not be
concerned with reflashing the PCM

WHAT YEAR?

hi oduyemi. kindly scaan the car with N5000, what ever cde u have will tell what the prblem is

THAT is false you have to get your obd11 code erease witch a code reader or a scan tool and after that everithing should be ok

Have the sensor changed. When the vehicles computer senses an error in the transmission it puts the transmission in safe mode. Being that its a newer car you might check with your local nissan dealership and see if it is covered under warranty. Good luck:)

Sounds true. The oxygen sensor regulates the fuel air (oxygen) mix for optimum performance with the least amount of fuel. If the oxy sensor malfunctions you'll get the incorrect fuel/air mix and waste fuel. Some vehicles see a 10% increase in fuel use with a bad O2 sensor.

That is FALSE. The radio has nothing to do with charging the keys battery. Some key batterys can be replace others get recharge through the key holder. Your Im pretty sure it can be replace, if not then more than likely you need a new battery or a new key. They are common to fail after several years.

That is true its part of the antitheft system.
