2006 Nissan Altima Repair Question
2006 Nissan Altima Engine stalls
2006 Nissan Altima 4 cyl Two Wheel Drive Automatic 53846 miles
I have a Nissan ALTIMA 2006 SL, I am having problems with the engine It stalls every week. When you put it on Neutral or Parking the car does not accelerate. But when I turn off the car then turn it on it starts working again but the Service Engine Soon light is still on. I went to the garage and had it scan with a scanner BOSCH KTS 200, the first time it triggered this message:
Pedal acceleration synchronization error. After the scan the signal dissapeared. This week I had the same problem I had it scan again but now it triggered another error: P2138: Unknown error.
I had the Airbag scanned too it triggered 3 errors:
- Front ABS sensor was triggered
- Front impact sensor communication fault
- Driver side front airbag igniter circuit - Open Circuit
How to fix this accelaration problem and Airbag if possible ?
The p2138 has to do with the accelerator pedal position sensor circuit, which is consistent with the pedal message and the symptoms of no acceleration..
This car has no cable going to the throttle but rather a sensor on the throttle that picks up a signal from a sensor at the pedal.
IF anyone has moved the throttle plate manually, then I would suspect the throttle position sensor at the throttle bore either needs to be relearned or replaced.
HAs the throttle bore been touched at all?
The Throttle bore has not been touched, I went to check it at the auto service. The guy told me I have to change the whole accelerator system which includes the throttle position sensor. Do I really have to change the whole system or just the throttle position sensor?
What about the problems with the Airbag system ?

I'll see if I can get testing procedures and I'll check on airbag. Bear with me.
I'm not sure what code numbers you have but I have learned there is a problem with the wiring harness under the front seats and that has been a fix by replacing it.
"ASSIST A/B MODULE [SHORT] [B1068] or [B1073] Front passenger air bag module circuits [wires] are shorted to each other.
ASSIST A/B MODULE [OPEN] [B1065] or [B1070] Front passenger air bag module circuit is open.
1. Visually check the wiring harness connection. 2.Replace the harness if it has visible damage. 3.Replace front passenger air bag module. 4.Replace the air bag diagnosis sensor unit. 5.Replace the related harness."
IF it has been deployed, I also learned this:
"HARNESS CONNECTOR DAMAGE IS COMMON AFTER DEPLOYMENT. In particular, the push in locking device (usually black) gets damaged if not released before removing the connector from the bag. Driver side common melting problems requiring clockspring replacement. The locking device also serves to release the airbag shorting bars so, if they are damaged or missing, you will get a "short circuit" code. Try with 2ohm - 1/4 watt resistors in the harness side and clear codes."
For diagnosis, this is where we start:
Turn the ignition key on and foolow the air bag light for the following patterns and get back to me:
You need to call the dealer with your VIN and ask about any open recalls, specifically pertaining to reprogramming or the crankshaft position sensor.
This may not apply to your current problem, but a reprogram for free accompanied by a potential problem fix will be worth it. I am still working on the problem as you described.
I ran the VIN, and found out the car was involved in car accident in 07/2007 and the air bag was deployed, that s why I think it s not working now.
I have problems reading the attachment of the Airbag system and the three first indications are missing.
The car was not part of any recalls too.
