I have 3 codes c1143-steering angle sensor, c1130 - engine signal 1, & p0102 - mass air flow sensor.

Question

I just replaced the rack and pinion, power steering pump, & power steering sensor. Now the vdc/slip/check engine light is on. I just got a new air filter. Do I need to replace all 3 sensors? Please help!!

Answer 1

if your alignment is really off the light will come on, you can do an alignment and see if it goes away. you can also adjsut the steering angle sensor with the OBD-II reader if it has the option. 

c1130- you can try to reset the code and see if it comes back, might be a bad ground wire.

P0102 Infiniti - Mass or Volume Air Flow Circuit Low Input

Try to clean the sensor first, with mass air flow sensor cleaner.

possible causes:

- Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor circuit poor electrical connection
