2007 Nissan 350Z Problems

Erratic or High Idle After Cleaning Throttle Body

The throttle body for the Nissan 350Z is known for carbon buildup, and requires regular, light cleaning to maintain peak performance. After cleaning the throttle body, many owners notice a very high idle, erratic (bouncing) idle, and unpredictable power surging. 

The cause is normal ECU adaptation: When the throttle body builds up carbon, the rate of airflow is slightly decreased. The vehicles computer reads this decrease in air volume, and adjusts the throttle body settings to maintain the proper engine idle speed. When the carbon is cleaned out, the ECU now registers too much air, and cannot adjust back to the original settings. While it is trying to change settings, the idle will bounce from low to high, and the car will surge forward at times. 

It has been recommended to simply wipe inside the throttle body every 12,000 miles, and never to touch the flap inside. Also, the cleaning procedure may be best left to a qualified technician.

The solution can be as simple as disconnecting the battery for at least an hour, having the dealer reset the computer, or, in extreme cases, replace the throttle bodies. 

Engine May Stall Due to Failed Crankshaft and/or Camshaft Sensor

The engine may stall at times due to a failed crankshaft position sensor and/or camshaft position sensor, These sensors can fail intermittently as they warm with the engine. Sensors on certain models have been recalled by Nissan and will be replaced as necessary. Please visit our recall section for this model to see if your vehicle is covered by this recall.

Ticking Noise From Engine Area Due to Faulty Fuel Damper

A faulty fuel damper can produce a ticking noise, which can be heard inside the cabin when the engine is idling. Replacement of the failed dampener should correct this problem.

2007 Nissan 350Z Recalls

Passenger Air Bag May Not Deploy

This recall affects certain vehicles equipped Occupant Classification System (OCS) control units manufactured by Continental Automotive Systems. A varistor in the OCS control unit may have been manufactured out of specification. Under certain conditions, this could interupt the signal between the OCS and the air bag control unit (ACU), causing the passenger air bag to be suppressed in an accident. If the air bag does not deploy when needed in a crash, the risk of injury is increased. Dealers will test the signal between the OCS and ACU with a special tool to verify proper function. The seat cushion containing the OCS hardware will be replaced as necessary. The recall began November 4, 2008.
