The year 2002 is known for a faulty designed heater core that o rings fail and it leaks right onto the pcm and the trans control relay.. passenger side look for wet carpet, maybe foul smell, and foggy windows hard to see out, due to moisture.. hope that helps

P0431


Well code 431 means the computer does not think the catalytic converter is working correctly. The engine computer uses data from the O2 sensors to monitor the cat.
The actual problem could be the cat, one of the O2 sensors, a fuel problem, or other things. The O2 sensors would need to be watched with a scanner to find the issue.

Code P0455 evaporative emission system leak ( large leak) 2002 Mitsubishi diamante


Could be a number of things...rusty filler neck, or a bad "vent solenoid." These are more common. The evap system closes once you are driving it to send fuel vapors to a charcoal canister, and if it can't due to a leak, your check engine light will go on.

Neutral light on magna th keeps flashing when in 1,2,3,and d, what should i be looking for?


Hi there,

The Diamante has an intelligent auto transmission.

When the "N" light flashes on your instrument panel, it means the onboard computer has detected an abnormaility within the automatic transmission.

If I remember correctly, the frequency of the flashing "N" denotes two possibilities:

a) 1 flash per second = Transmission fault:

You will need to have the fault codes extracted from the vehicle's computer, to determine the area of your transmission which is at fault.

b) 2 flashes per second = overheated transmission

Pull over and allow the engine to idle for 2-3 mins, while in PARK (this will aid the transmission fluid to flow throughout and help to cool the trans fluid down a little). You will need to have the fluid inspected and possibly the fluid temp sensor also.

Cheers,

"If this has helped you in any way, please rate this solution"

When in drive the neutral indicator light flashes and the car drives sluggish. it is a mitsubishi diamante. 2001 model.


Check your ATF cooling system. Your transmission fluid is overheating. This might be after a hard drive. The fluid might need to be replaced too.
