Question about 2005 Nissan Quest 3.5
DTC P0113 - Intake Air Temperature Circuit High Input.The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.
DTC P0183 - Fuel Temperature Sensor Circuit High Voltage.
I suggest to check wire connections.

Fuel injected or carb? Make sure fuel line itself is clear. Some pumps are designed to self regulate (carb systems) some continually pump and a psi regulator sends back the excess fuel back to the tank (fuel inj systems) If the line is obstructed then pump can't deliver fuel fulltime.
If you think pump is not on consistent, try running a dedicated wire through a switch directly to the pump. If it works then you are looking for an electrical fault going to pump. Good luck.

well i know on the v6 that is true you replaced all of them. Not sure of 4 cyl but seems like it should be the same. Also I know on the v6 the variable valve timing set up sometimes did some weird failures triggering a cam sensor code. It could be anything from sludgy oil hanging up in the vvt hub or clogged passages or bad solenoids. but before going into all that(well besides maybe an oil change) I would go for the crank sensor.

Have the compression checked....Hook a vacuum guage to the engine...This should give you a good idea of how much life is left in the engine.....

i just had the same problem in my bmw 325i. Probably vaccum leak or exhaust leak. Check that nothing came loose in these areas. It takes time for your car to learn the new CPS (cam pos. sensor) so give it a few days and reset the code again and see if it works.

yes to your first question only tests the bulb

Testimonial: "THANK YOU! It took me awhile just to find out about the self-diagnostic. The service manual wasn't as helpful."
