DII, 2000, 60k miles, stack. I had my MIL came on about 4 month ago. The car was driving with no problem at the beginning. Now its just sh*&^. No power, 3 amigos came on, and more. Here is the list of codes i got.
P0734
p0590
P0154
P0134
P0155
P0171
p0141
p0161
p0306
pending codes:
p0174
p1174
p1536
p0560
p0650
Where should I start.... Please help....

 

Start with a tune up (magnecor wires and plugs) and replacing all 4 O2 sensors and then clear then and see what comes back.

P0734
(32)
* Ratio monitoring,
implausible 4th gear
ratio
No apparent effect On Off

p0590 - not sure

P0154 O2 sensor circuit no activity detected (bank 2,
sensor 1)
Front sensor RH bank open circuit

P0134 O2 sensor circuit no activity detected (bank 1,
sensor 1)
Front sensor LH bank open circuit

P0155 O2 sensor heater circuit malfunction (bank 2,
sensor 1)
Front sensor heater RH bank - short/open circuit

P0171 System too lean (bank 1) Multiplication injector adaptive fuelling - lean limit
exceeded LH bank

P0141 O2 sensor heater circuit malfunction (bank 1,
sensor 2)
Rear sensor heater LH bank - short/open circuit (NAS
and EU-3 only)

P0161 O2 sensor heater circuit malfunction (bank 2,
sensor 2)
Rear sensor heater RH bank - short/open circuit (NAS
and EU-3 only)

P0306 Cylinder 6 misfire detected Excess emissions level of misfire detected on cylinder
No.6

pending codes:
P0174 System too lean (bank 2) Multiplication injector adaptive fuelling - lean limit
exceeded RH bank

P1174 System too lean (bank 2) Additive injector adaptive fuelling - lean limit exceeded
RH bank

P1536 Air conditioning compressor request range/
performance
ATC compressor clutch relay open circuit

p0560 - not sure
p0650 - not sure

 

Start with the tune up, I would hold off on the O2's until that is done in my opinion.

 

Some of those O2 codes (134, 154) are indicative of dead sensors so they will definitely need to be replaced from my experience.

 

Sorry I missed those, I stand corrected.

 

Spike what do you make of P0734 and P1536. I have never seen those before. P1536 sounds like a bad compressor clutch not sure about P0734.

 

1536.......I have that code as well. My AC will blow ice cold but if I drive for long periods of time (long road trip), it may not blow cold for several minutes or longer, then all of the sudden, it starts blowing ICE cold again. The process continues. My mechanic told me he thought it was the expansion valve.

GODSDOZER

 

See what happens when you don't take care of problems as they come up, 4 months before you got your codes read, that is insane.
So as already mentioned, a tune up with wires, 4 02's, way to early but you are killing them and a MAF to clear the the lean codes and the 734 tranny code. In the mean time, quit driving it before you trash it.

 

Thank you all very much for your advises. For some clarification, this is my dads truck, so thats why it took 4 MONTH after first problem appeared till it almost died. Now hes not driving this thing and thats why he asked me to take a look. When I plug my scanner, I was SHOCKED!!! 14 CODES?!! When I looked online, I already told him hes gonna need a good tune up plus couple O2 and possible MAF. I just wanted to make sure Im on the right track and may be there is something else.
I appreciate everyone opinion..
Ill let you know on progress....


PS. I personally owe DII, 2000 with 80k and just last week did a tune up after I got 3 codes. P0300, p0302, p0303. Plus I had to replace one of the coils. Now it runs like new....

 

Cleaning my MAF, cleared that 4th gear code for me. Found the solution on this board.
