Hello.
I've been annoued by this same fault for now half of year.
All started suddenly, I was driving to work at morning and after 1 kilometer, car went to limp mode.
Restarted the engine and everything was back to normal. After work, I was trying to start the car, but limp mode came on right away.
Couple of restartrs and everything was back to normal again.
I read fault codes and got these:
P1500 - Electronic Throttle Control Motor Failure
(08) - Not present
P1550 - Electronic Throttle Control Power Management
(04) - Not present
Since then, I've replaced sparks, oils, filters, lambda1, etc.
Also cleaned throttle body andreplaced/cleaned engine ventilation hoses
No difference.
Then I figured that fault could be on throttle body, so I replaced it with OEM throttle body.
Everything was fine, until these came up:
P0170 - Lean Exhaust
(02) - Not present
P1525 - Limp Home Position Error
(00) - Not present
P1550 - Electronic Throttle Control Engine Stop
(08) - Not present
P1526 - Throttle Position no Adaption
(08) - Not present
Lean exhaust must be because sometimes engine won't start right away when fault is on, so I tried to get it started and kept starter motor running maybe too long.
Usually engine does start right away when fault is on, but it goes to limp mode right away.
These are the latest fault codes I've been getting for last 4 months now:
P1525 - Limp Home Position Error
(00) - Not present
P1550 - Electronic Throttle Control Engine Stop
(08) - Not present
P1526 - Throttle Position Adaption Error
(04) - Not present
and
P1525 - Limp Home Position Error
(00) - Not present
P1550 - Electronic Throttle Control Power Management
(04) - Not present
P1526 - Throttle Position no Adaption
(08) - Not present
I can drive my car normally, maybe sometimes acceleration pedal "feels" funny and I've noticed that my fuel consumption have been risen from 8-9 l/100 km to 9-10 l/100 km since this fault has been on.
Also I have noticed that fault comes up (limp mode or engine won't fire up right away) when weather is moist and near 0-5 degrees of celcius.
Otherwise, only thing that reminds me of this problem (when its not showing itself) is that when I switch power on, dashboard shows yellow fault light, but it goes of if engine starts normally. And fuel consumption has risen.
Long story short, where do you guys/girls think I should look next to solve this problem?
I've attached some live data from my car, where I pump acc pedal on and off, just to see if there's any errors or wrong values.
Any help would be nice, because weather is going to worm up soon and more limp modes are expected..
Thanks!
