Toyota Avensis 2.2 4D4 2002 - Engine only runs while starter operating, code P0200 #

Posted by Paul Howd on January 24, 2011, 5:02 pm

Year of Manufacture *: 55 plate
Engine Size and Code *: 2.2 4d4
( Optional ) Scanner Used: X431
( Optional) Fault Codes: P0200

Background...

Battery light came on while driving and battery gradually discharged untill engine misfired and stopped.

After recharge (and with the expectation of diagnosing an alternator fault) engine would fire up on cranking but die as soon as key released.

If Key held in crank position engine will run and even rev but die as soon as key released.

Autodata is of only limited help here, I was hoping at least for a wiring diagram that might indicate why the engine would run in crank position but not run position but to no avail.

What did seem clear however is that autodata seems to suggest that almost everything that goes wrong with one of these ends up requiring a reflash!

Is it possible that the battery running flat while running has damaged the ECM or scrambled its software?

Before I pass this on to the Yota dealer I was just wondering if anybody had any thoughts on the matter?

Have you checked all the fuses to see if you blew one through charging or when the electrical system was struggling? Chances are this is going to be something simple.

I would check the ignition switch first had a similar problem with a honda many moons ago

I didnt recharge the battery so I dont really know what procedure the owner followed apart from disconnecting the battry before connecting the charger.

I agree that it might well be something simple but with an almost complete lack of any information (Autodata??) it is difficult to know where to start looking (A wiring diagram would have been nice at the very least)

I am not a great fan of digging into wiring issues anyway owing to being R/G Colour blind. Doing so without a wiring diagram is like finding your way around a strange city with no map and the road signs removed! (Less of a problem in earlier simpler times when it was pretty obvious what each wire actually did and there was no delicate electronics to destroy if you probed the wrong thing)

As I said, I am likly to pass this on anyway since even if I do solve tha starting issue I still have the alternator to deal with and since they seem to run out at about £400 (Plus VAT)AND looking like a not so nice job anyway! I am not sure I want to be further involved anyway.

I was just wondering if anybody had come across the "Nonstart after flat battery" scenario before as a specific issue.

Ho Humm.

Interesting further news....

Aparrantly this morning (after having been left overnight with the battery connected) The engine did start and idle normally, However the throttle responce is very flat, it only revs sluggishly and there is insufficent power to actually drive anywhere.

It is booked into Toyota and If I get any further news I will let you know.
