2009 Nissan Maxima

2009 NISSAN MAXIMA

MSRP: $29,290
Gas Mileage: 19 mpg city / 26 mpg hwy
Engine/s: 3.5L V6, 24 valve, 290 hp @ 6400 rpm
Transmission: VAR speed Automatic

Though the chassis and sheetmetal are new, performance will come from the standard 3.5-liter DOHC 24-valve VQ-series V-6 engine that powered the previous-generation Maxima and nearly everything else in the Nissan fleet. This revised engine is now rated at 290 horsepower and 261 lb-ft of torque, an increase of 35 horsepower and nine lb-ft of torque over the 2008 Maxima engine. Will such impressive output make it a torque-steering beast? Nissan engineers say no and claim to have implemented appropriate countermeasures.

When I tried to start it both batteries were dead.

QUESTION:

I needed to move my truck to another location so I could work on the speedometer problem. When I tried to start it both batteries were dead. A battery charger was connect but with reversed polarity. Before I could stop it the charger was tuned on. I immediately turned it off and disconnected it. I've charged the batteries but now the truck won't start. I found a 10 amp fuse burnt (in a panel in the engine compartment). When I changed the fuse some light on the dash panel came on - in a dim state- and stayed on, until I removed the fuse. The truck won't start although it will turn over. The ignitor light does not come on any more. This is a 1999 E-450 cube van with a Power Stroke Diesel. Can you shed some light as to what might have happened to the electronics of the truck My biggest fear is the computer.

ANSWER:

Because you hooked your charger up backwards it likely you blew one of the fuse links at the starter solenoid on the passenger side inner fender. I'm enclosing a schematic for the fuse links. Take a 12 volt test light and move down the harness where the fuse links are located and check for 12 volts. I suspect you have blown one or more.

How to Scan for Trouble Codes (Check Engine Light)

How to Use an Engine Scanner The engine code scanner has made automotive repair easier than ever. When the check engine light comes on while driving it means there is a system that is having a problem. With the trouble code scanner you are able to retrieve the trouble code stored in the vehicles computer. Once the system has been identified replace the shorted senor or other repair and clear the codes out of the vehicle's computer. Once the codes have been cleared the computer will go into relearn procedure and run any number of system monitors to determine if the trouble has been properly repaired.

When the Check Engine Soon Light comes on , your first instinct is to pull over and check out the situation. This is not necessary. This is the vehicles way of letting you know at its earliest stage that an error has occurred. No need to panic. If you have been driving with that all annoying light on, remember this : Your gas mileage will improve if the necessary repairs are made.
