[03 Impreza Engine Code: P1559]

After driving about 40km my car throws this engine code

P1559

Chrysler, Dodge, Jeep: Cruise Control Power Management Mode

Seat, Audi, VW: Idle Speed Contr.Throttle Pos. Adapation Malfunction

 

I have manual swapped it and have tried both manual and automatic ecu. It does the same thing.

 

I have wired the speed sensor driectly to speedometer. The ecu isnt getting a signal and so the engine light comes on. Could that be contributing to the p1559 code?

 

Any help would be much appreciated.

 

The video is what it does at a stand still. If moving its like its gonna stall and bunnyhops until I let off throttle

 

 

[Throwout Bearing Constant Contact?]

Should the throwout bearing have constant contact with the pressure plate? if not how should it be adjusted?

 

I have a NA 03 Impreza Wagon. Just clutch cable

 

Thanks in advance

hmm... maybe on top on the tunnel under all the plastic stuff? My 99 STi had the ABS computer or something related there... so know they use that spot for "things".

 

Nope nothing there

How about on the passenger side of the transmission tunnel around the handbrake, gearshift area... under the carpet obviously,

 

I didnt see any wiring going there? I cant have a look till friday though I work out of town.

yours pics are showing the right side of the steering column... it should be left above the clutch pedal.

 

Theres nothing there. I put the clutch in

Thought it might have been. No idea what the deal is then.

 

Have you checked over the ECU pinouts to make sure everything is in the same place on the old ECU as it is on the new one?

 

The manual ecu had 3 connnectors plugged in and the auto had 4. Thats why Im thinking its built into ecu but I cant find anything online?!?

What's the box hanging under the steering column?

Looks to be the right shape and the plugs look about the same too

It is not located there! I just did a manual swap. Ive put in a manual ecu but I want to disconnect the tcu

This is where it is on Legacy’s and i’d bet they didn't change the location much for Impreza’s.

 

The more important question is why do you need to find it anyway?

Thats where I checked first. Ive removed the dash and still cant see it

I am trying to locate the tcu in my 2003 Subaru Impreza Wagon. Ive removed the dash and still cant see it. My ecu has a model number on it that starts with PCM so is intergrated into the ecu?!?
