hey guys,

long story short, i accidentall crossed the battery on my 2003 D2 while installing a extra battery i had laying around. The engine will barley run now and boy do i have codes.WTF am i gonna do. i just spent 6k $ on a rebuild and i did this while in hte parking lot of the shop. Please guys i need help.


i have the following codes
1451
0414
1482
1884
0445
0448
0102
0340
0134
0154

 

So you connect positive to negative and negative to positive? That very well could have fried your computer. None of the codes listed show up on the code list I use.

 

clear the codes and try again. most of these i don't know. here are the ones i could find. it may have fried the computer...

102 - Mass Air Flow Sensor Low Out of Range Fault
340 - Camshaft Position Sensor Signal Error Fault

 

whoa, that's a lot of codes. I say you fried it but clear codes and get back to us.

 

None of those were there before? Clear them and see what comes back...


P0414 SAI vacuum solenoid valve short circuit to ground
P1415 Secondary Air Injection System – Malfunction Bank 2 RH (Insufficient SAI flow
during passive test)
P0102 Mass or volume air flow low input MAF signal < minimum threshold, which is speed
dependent
P0448 CVS valve short circuit to ground
P0340 Camshaft position sensor circuit malfunction Open/short circuit to vehicle supply or earth
P0134 O2 sensor circuit no activity detected (bank 1, sensor 1) Front sensor LH bank open circuit
O2 sensor circuit no activity detected (bank 2, sensor 1) Front sensor RH bank open circuit

P1184 is a doosey:

(11)
* CAN message:
Engine friction invalid
No apparent effect. On Off
P1884
(18)
* CAN message:
Throttle position invalid
Substitute throttle angle of 50% adopted. No
kickdown. Operates in economy modes only.
On On
P1884
(19)
CAN message: Engine
temperature invalid
Substitute engine temperature derived from
other inputs. No apparent effect.
On Off
P1884
(20)
CAN message: Road
speed invalid
No apparent effect On Off
P1884
(33, 34)
* CAN message:
Engine torque invalid
Substitute engine torque of derived from other
inputs. May affect shift quality.
On Off
P1884
(35)
* CAN message:
Engine speed invalid
Maintains current gear in low range, limp
home mode in high range. Shift pressure to
maximum, harsh gear shifts/engagement.
On On
P1884
(37)
CAN message: Engine
air intake temperature
invalid
No apparent effect. On Off

 

Woow, that is one code for each light on a Christmas tree

 

For future reference, batteries are labled + and - right next to the post.
Positive battery posts are larger than negative posts.

 

ok i replaced my ECU but i need to reprogram it to make the car start!!!!


anyone know of a good shop with auto logic near detroit east side

 

so clearing the codes didn't work?

 

That was fast. I believe you need to take it to a shop with the appropriate diagnostic software like testbook or whatever.
