Need Help With Galaxy Loss Of Power.

[Chris62]

Hi,

I have a 96 Galaxy 2.0L, about a week ago my wife run the petrol tank rather low and the car started to kangaroo. Filled up with petrol and problem pesisted (coincidence maybe).

The car now kangaroo's quite badly when over 30-35mph or when going uphill. Seems ok at 30mph on level ground.

I changed the fuel filter as a starting place but this did not make any difference. I have borrowed a code reader and used this with Scantool. The following DTC's are reported

P1405 and P1413

 

Now I need to know what these codes mean, I've looked on the link stevie m posted on this forum but those codes are not listed.

I have found the following to start with

from an eecv error code list:

P1405 Differential Pressure Feedback Electronic Sensor circuit Upstream Hose.

P1413 Secondary Air Injection System Monitor circuit Low Voltage.

 

and from somewhere else (can't remeber where now)

P1405 Ventil 2 fur Abgasruckfurung (N213) Fehlfunktion :lol:

P1413 EGR Different pressure sensor signal too high

 

Are these descriptions the same thing in different technical speak? And what do I have to look at or replace to fix it.

 

Thanks for any help.

 

Chris

bumped up for you hun, cant help you but i can bump the topic :lol:

It's an EGR (exhaust gas recirculation) fault. Basically the EGR valve is stuck (partly) in the recirculate position which leads to a lack of air and kangarooing. Either the EGR valve itself is sticking, or maybe one of the pipes controlling it have split or come loose.

 

If it is stuck you could try some injector cleaner and an italian tune up to free the valve. (i.e. rev the bollocks off her in 2nd or 3rd gear).

I gathered it was to do with EGR :lol: I've had a good look under the bonnet and did find a possible problem. If you follow the 4 metal pipes from the exhaust manifold, they join into one pipe, further along this there are two pipes that come off it quite close together. Hoses run off these upto some sort of sensor block on the bulk head. Now the part that the hoses connect to bolts onto the sensor block with two nuts, one of these was backed off about half way and this was allowing it to come away from the sensor block.

The nut was not loose, quite tight on the threads actually. So tightened it up so it secure, cleared the DTC's and went for a 5 mile run. Checked for DTC's when back at home and none showing. Performance wise the kangarooing has stopped although there is a little hesitation when starting to accelerate.

Put everything back and went for another longer run, performance was the same, no kangaroo but hesitation on acceleration. Checked DTC's and they have come back, argghhh.

 

@seatkid, have put some petrol cleaner in, thanks. Can't do anyharm :lol:

 

Any help gratefully recieved.
