Well, here's the problem. When running full open throttle the car will sometimes cut out leaving me with no control of the throttle. The car will idle but not rev. When it happens I have to shut it down and do the throttle position reset to get it running again. The SES light is also on. It's been happening at the track, usually around the top of 2nd gear. Very embarrasing!

I had a tech at the dealership where I work pull the code with his OBD scanner. He said it had something to do with the pedal position sensor. He also said the throttle was only opening to 87% with the peddle to the floor. My S-AFC2 shows the throttle opening to 100% but the tech said the OBD scanner was better to go by. He was unfamiliar with Nissans drive by wire system and couldn't tell me anything else.

I have an appointment with Nissan but wanted to see if anyone here had any ideas.
Thanks

 

I think that 02-03's had a recall do to an issue with the pedal stop. I guess you can over extend the pedal past the stop and it can cause problems with the sensor and cause you to go into limp mode.

 

Wow, that sounds like exactly what's happening. I'll mention that at the dealer. Having the throttle only open to 87% still has me wondering though. The car feels really strong.

 

on the 5.5 gen, the throttle body never opens 100%.
You'd need the TS ecu to let it open all the way.

 

OK, that makes sence. I thought it closed a little as it approached redline but could open all the way in the lower RPM. I wonder why Nissan did that.

 

87% changes the airflow direction which might be more optimal than 100.
