Hello everyone. I need some help/advice.

2003 350z touring edition 100k+ miles. 6spd.

Symptoms:

1. check engine light on all the time.

2. when i start car and turn the wheel; the car brakes violently as if ABS is kicking in. If I turn on VDC right after i start the car and before i move it or even move the steering wheel; then car does NOT brake violently but the SLIP light comes on.

3. some times the car goes into a 'limp mode' state... i can rev it up and pick up speed.. it seems more as if i lost a cylinder (bad spark plug) if i drive it enough it just fixes itself.

4. when i start the car it takes about 6 seconds to start (cam sensor bank 2 PROBLEM FIXED TODAY)

I took it to my buddy at nissan dealership. he pulled the following codes:

ENGINE

1. CMP SEN/CIRC- B2 (P0345)
2. CMP SEN/CIRC- B2 (P0345)
3. HO2S1 (B2) (P0152)
4. HO2S2 HTR (B2) (P0057)
5. TCS C/U FUNCTN (P1211)

ABS

1. ENGINE SIGNAL 1 (C1130)
2. ST ANG SEN CIRCUIT (C1143)

I replaced the cam sensor bank 2 (driver side) and that took care of CODES 1 AND 2 FOR THE ENGINE.

I will buy the o2 sensors to fix the CODES 3 AND 4 FOR ENGINE.

P1211 says it might be the ABS ACTUATOR OR ABS PARTS

C1130- says ENGINE CONTROLY SYSTEM MALFUNCTIONING... not sure what to do for this one.

c1143- STEERING ANGLE SENSOR..

HERE IS MY QUESTION:

1. according to the symptoms above should i focus and replace the steering angle sensor c1143 first or should i focus and replace the ABS ACTUATOR P1211 first..

2. what about the car going into a 'limp mode' kind of state? i've replaced all 6 sparks plugs.. so i know thats not it.. what else should i look into? intake sensors? fuel system related sensors?

thanks!!!

 

could be more then just a plug but a coil in one or more of the cylinders if you think it could be something with the plugs and that didnt fix it. switch it around c if the code follows? cam sensor i had the problem but it went away and a year or more later and it still hasnt come back. so no clue on that part sadly. doubt its a coil or plug because it would b p030X(# of cyl.) clean throttle body maybe if got nothing else to try until someone who has more knowledge then I shows up to answer.

 

The steering angle sensor (or adjustment of it) could be at fault for the ABS kicking in when turning the wheel. Seems like a lot of random issues, was this car in a bad accident or flooded or something?

 

its just weird how it starts to misfire "limp mode" style, loose power, but i can still get up to speed and rev.. i will clean the tb. any other suggestions?

 

never been in an accident. no flood either. it has had 2 turbo kits and built engine, back to stock engine.

 

anyone else?

 

did you ever figure this out? I’m having the same exact issue
