SOURCE: my 2005 altima idles high and engine code

Your Altima will require an idle air volume learn after cleaning. This procedure will set your idle speed. If the code keeps recurring after the IAVL your throttle chamber may need to be replaced.

If the throttle body is dirty or if you have a vacuum leak, or if the Idle Air Control Valve is bad, these will all cause high idle.

DTC P0506

Circuit Description

The throttle actuator control (TAC) motor is controlled by the powertrain control module (PCM). The DC motor located in the throttle body drives the throttle plate. In order to decrease idle speed, the PCM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the PCM commands the throttle plate open allowing more air to pass the throttle plate. If the actual idle RPM does not match the desired idle RPM within a calibrated time, this DTC sets.

This diagnostic procedure supports the following DTC:
DTC P0506 Idle Speed Low

High idle problems


There could be several issues causing this problem. For one, I assume you meant 2000 rpm, not 20000 as the engine would have expired before reaching that number.

Checking the computer codes on this would be the safe thing to do as the Throttle Position Sensor could have failed or is sending the incorrect information to the ECU. Another possible issue to look for is a failure of the throttle return, if memory serves there should be a spring on the backside of the throttle body. If the spring is broken or missing, this could leave the throttle open enough to increase the rpm. I would also check the throttle body/throttle blade for dirt. Normally a dirty blade results in a decrease of rpm but it might be possible that it is sticking and not closing as it should. There are special throttle body cleaners available - do not use carb or brake cleaner as they could damage the throttle body. Let me know if any of the above helps.

Idle out of control.


check all your vacuum hoses and the throttle body itself for a vacuum leaks if the hoses replace as nessasary if to check for throttle body get can of carb cleaner and spray around base of throttle body and sides not in it if idle raises you have a vacuum leak goto a good parts store and ask for a rebuild kit don't goto auto zone or advance they don't carry them

Idle at 1500 to 2000 rpm


Most likely the throttle body gasket (between the throttle body and the intake manifold) is leaking.

Loping and high idle


You are really onto it! Either the TPS or the cable from the peddle. Do check the cable first. Frankster016
