Question about 2004 Nissan Maxima
Been having strange things going on with car, (press on gas and gear seems to not go into gear but then jumps into gear, also from park to drive car jumps, lately, twice in last week felt like a heavy weight on front of car and all a sudden car stopped as if it had no power -check engine light went on and VDC or VCD went on- stopped car turned off and re-started and I was able to make it home. Took it to auto zone and was given four different codes that all seem to relate to the Electronic Throttle System. I had thought it was my transmission, would this throttle failure have effects as I've described above? Can anyone help and give me some advice? The codes are, C1131, P1726, P1800 and P2135 Thank you, Christal
Call a Nissan dealer to see if there is a recall on your car. That problem has been addressed with recalls a couple of times.

TCS is Traction Control System,and all TCS's are controlled though the Anti Lock Braking (ABS) system.Here's how it works:Each wheel,or in some cases,only the drive wheels have a speed sensor mounted near the hub or axle,and sends a speed signal to the PCM (Powertrain Control Module).The PCM monitors wheel speed continuously,and if it sees a speed out of the ordinary,say for example the right rear tire is spinning and traveling at a much higher speed than the left rear,the PCM will pulse the brakes through the ABS system on the right rear to slow down the right rear so that the left and right wheel speeds match up,this is how the traction control works.So,if you have a TCS problem,the PCM will see this and set a Dignostic Trouble Code (DTC).You need to pull the DTC's out of the system with a scan tool,diagnose and repair the DTC's.It could likely be something as simple as a malfunctioning wheel speed sensor,but you won't know until the codes are pulled out,as this will point in the general direction.Good luck.

You may have bad solenoid, starter/battery/solenoid connections, or gound.
Check voltage at starter solenoid when somebody turns key to start. That is where the starter switch, or relay, sends the voltage to pull in the solenoid coil through small wire. I think the solenoid is on the starter for this car, but it may be separate. Autozone has an excellent web site with car-specific repair guides and instructions. You should see 12V at solenoid every time the key is turned to start.
Check big power cable to starter that runs direct from the battery for tight connections. If you have a separate solenoid, then another big cable runs from it to starter. A loose or bad connection could be the culprit. Also check starter mount bolts. They need to be tight for a good solid electrical ground. You also need good ground from frame to engine. Its a long shot, but sometimes the ground straps come loose or burn. You can easily check this by measuring resistance between engine block and negative battery terminal. It should be zero or darn near zero (less than 1 ohm ?).
The solenoid is really a heavy duty swich to handle the high amp load to the starter. It works by a coil that pulls in the big switch. The coil operates from the starter switch and needs onlyt low current and small wire. If the coil wires burn up or there is a bad connection, it won't work. Hope this helps.

I discovered that its the throttle body sensor. Its not sensing the postion of the foot pedal. The throttle body has a sensor that is linked to your gas pedal via a cable. The spring that the repair man mentioned could be the issue. The sensor then communicates to the computer the position and then computer then applies fuel, the mass air sensor then will communicate to the computer and the computer will then allow more or less air to fuel ratio. So if your stomping on the gas and there is not any response, then your throttle body sensor is most likely going out.

You may want to have someone else take a look at it. The Nissan P1800 trouble code is not a transmission control problem. It is described as follows:
Trouble diagnosis name: VIAS control solenoid valve circuit.
The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to ON/OFF signals from the ECM. When the solenoid is off, the vacuum signal from the intake manifold is cut. When the ECM sends an ON signal the coil pulls the plunger downward and feeds the vacuum signal to the power valve actuator.
DTC detecting condition:
•An excessively low or high voltage signal is sent to ECM through the valve.
•Harness or connectors (The solenoid valve circuit is open or shorted.)
•VIAS control solenoid valve
Check your vacuum hoses to make sure they are in good shape and are securely attached Aslo check the wiring harness is ok and securely attached as well. If they are, you’ll probably need to replace your VIAS. It's right next to the throttle body.

CODE PO1800 VIAS CONTROL SOLENOID VALVE CIRCUIT. I DID NOT SEE CODE PO650 BUT CODE PO1800 IS A FAULTY VIAS CONTROL SOLENOID VALVE.
