Though there appears to be no discernible loss in power, I have had 7 instances within 8 months where the diagnostic Codes 0304 (Knock Sensor) and 1003 (Park/Neutral Position Switch)have appeared, always together. Each time I have manually extracted the diagnostic trouble codes and reset the Control Module, but I have grown increasingly agitated. Trophy Nissan suggested I ignore the codes and reset the Control Module, indicating that Code 0304 is common. As for Code 1003, I have a 5-speed and it doesn't start unless the clutch is depressed, so why would I be getting that code?

Perhaps I am experiencing a problem with the Control Module. I would appreciate any guidance which may help to resolve my continued problems with the these codes and/or the Control Module.

The '99 Maxima factory service manual shows that Engine Control Module terminal 27 is connected to ...
- (automatic) the Park/Neutral Position switch.
- (5-speed) the Reverse Position switch. This part is also called the Back-up Light switch.

Verify that both back-up lights are functioning. Replace any burned out bulbs.

Check the wiring and connector of the Reverse Position Switch on your transaxle case. Identify connector F32 which has four terminals in a gray plastic shell. This connector is easy to see but not so easy to reach. With the hood open, look down at the transaxle with your line of sight passing down behind the black plastic engine air intake duct. You will see the starter motor. Connector F32 is near the starter motor, just one inch away, toward the rear of the car.

Disconnect F32 and observe that the connector half which leads toward the Reverse Position Switch has four terminals. With the latch oriented at the 12 o'clock position there are two rows of two terminals each. The upper row is numbered 1,2 (right to left). The lower row is numbered 3,4 (right to left). With the transmission in Reverse there should be continuity between terminals 1 and 3. With the transmission in Neutral there should be continuity between terminals 2 and 4. With the transmission in any other position there should be no continuity. Terminal 4 should have continuity to body ground, regardless of transmission position.

If you have the part number you can type it in and look it up on-line. A lot of their prices are cheaper than most dealerships.
