Discuss the causes and fixes for C1143 Infiniti OBDII Code
-
Depends on what the problem is. If you had a wheel alignment done lately or your vehicle needs and alignment, the sensor needs to be reset. Some alignment shop may have the tool to reset the sensor, but if they don't you need to have the dealer reset the sensor for you.
-
If this is bad can it trigger VDC AND SLIP light on g35 and also no power or acceleration at all?
-
Can trigger the VDC and SLIP lights, but won't cause the no power situation. Are there any more codes?
-
No but the throttle body doesn't open at all with full throttle so we were thinking the steering angle sensor is the cause
-
More than likely is the throttle body. Try cleaning the throttle body:
-
Reply same question please.
If you change the transmission, then the Transmission Control Unit (part of the valve body) is not compatible with the Engine Control Module (ECM). You need to either reprogram or replace the TCM
-
I took it to tranny shop specialist and they said the tranny works perfectly fine and if it wasn't compatible it would be in Limp mode and stuck in 3 gear and wouldn't go above certain speed. Not that case for me I can go any speed just takes time. But the throttle body doesn't open at all when I floor the gas pedal, can it be a bad ground wire, the volts is .98 out of 5.0 so nothing

good afternoon! Please help me with my errors

I hope very much for your help!!! -
Start by clearing all the codes, and make sure the battery terminals are clean. The C1143 means that the steering angle sensor is not reading properly or your G37 is out of alignment
-
thank you for reply!
it is installed behind my steering wheel ( the steering angle sensor)? -
hi! I repaired the steering angle sensor, and i need clear errors? or automatically calibrated? sorry for my anglish) google translate

All the codes you have are related to the 4-Wheel Active Steer system, but if you also have the C1143 code, then you should start by replacing the Steering Angle Sensor, which is behind the steering wheel.
