P060e Control Module Throttle Position sensor, check all voltage and ground inputs to the ECM for an open circuit or high resistance. The computer will clear this code after three consecutive ignition cycles with no failures. Hope this helps out some.

I would use Gumout and an old toothbrush, usually works good to get the carbon for the throttle plate and throttle body.

SOURCE: I went to a local

Definitely clean that throttle body...can do it yourself for around $7.

Instructions for doing it without removing the throttle body.

1. Disonnect the battery....very important so your stepper motor isn't ruined when moving the butterfly.
2. Remove the plastic resonator on the top of the engine (The black piece that says 4200 on it)
3. Remove the large rubber hose from the throttle body.
4. Clean away, with throttle body cleaner or Seafoam, I just use the blue shop towels to clean in there. Could use a plastic bristle brush also for more elbow grease. Be very careful, as the butterfly will cut you very easily, very sharp edges. Make sure you get all the gunk out of there, including any edges of gunk that may have formed, preventing the butterfly from opening and closing properly. Needs to be nice and shiny.
5. Hook the resonator and hoses back up, don't forget the little pcv hose on the front right corner of it.
6. Hook the battery back up and drive around for 20 minutes or so with all accesories OFF. The computer will relearn a properly functioning throttle body at that point.
7. Enjoy a little bettery gas mileage and horsepower

As far as the injector cleane....Buy a $10 can of Seafoam, that will clean the injectors. Look on Youtube on how it works, good stuff.

SOURCE: 06 chevy trailblazer with fault

DTC P0506


The throttle actuator control (TAC) motor is controlled by the engine control module (ECM). The DC motor located in the throttle body drives the throttle plate. In order to decrease idle speed, the ECM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the ECM 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

- DTCs P0068, P0101, P0102, P0103, P0106, P0107, P0108, P0112, P0113, P0117, P0118, P0120, P0122, P0123, P0171, P0172, P0201, P0202, P0203, P0204, P0205, P0206, P0207, P0208, P0220, P0121, P0222, P0223, P0230, P0300, P0336, P0442, P0446, P0449, P0452, P0453, P0455, P0462, P0463, P0496, P1516, P2101, P2135, P2176 are not set.
- The engine is operating for at least 60 seconds.
- The engine coolant temperature (ECT) is more than -60°C (-140°F).
- The intake air temperature (IAT) is more than -10°C (-14°F).
- The barometric pressure (BARO) is more than 65 kPa.
- The system voltage is between 9-18 volts.
- The vehicle speed is less than 1.6 km/h (1 mph).
- DTC P0506 runs continuously when the above conditions are met.

- The actual idle speed is approximately 100 RPM lower than the desired idle speed.
- The above condition is present for 5 seconds.

- The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
- The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.

- The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
- A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
- A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
- Clear the MIL and the DTC with a scan tool.

Where is low idle sensor on 2006 chevy trailblazer six cyl it idles low and was told to clean sensor

Just my opinion, I'd check for applicable trouble codes, first. Some of the national brand auto stores will check codes for free. If you want to check codes, yourself, at the least, you need an obd2 code reader that will check po codes as well as manufacturer specific codes. See if anything points to tac/throttle actuator control?
There are also accelerator pedal position sensors that you need to check. If you want to clean throttle body, that's fine.

Dealer says code P0506 for my check engine light and that it is caused by air pump emmisions

Just my opinion, but dealer is blowing smoke up there! Clean your throttle body. This is idler control code. It is VERY common for our TB's throttle body to gum up and get clogged with carbon, because we don't have a pcv system. Disconnect the battery, clean the throttle body, best done if you remove the throttle body. You can even re-use the plastic o-ring/gasket many times over. I find that using Seafoam to clean with plastic bristled brush is the best. Seafoam is sensor safe and cost about $9 a can. Look up on the TUBE, there are many videos there showing how to clean a Trailblazer/Envoy throttle body. Very easy and inexpensive. After that's done, clean that throttle body at least once a year. You'll get better gas mileage with it clean.

First thing to do is to clean the throttle body, this code is indicating a lean condition. The throttle body needs to be cleaned on the front and back sides, this means taking it off the engine. During the cleanng, the battery should be disconnected to reset the computer.

Chevy trailblazer 2007 P0506 & P1400 what are the solutions for these codes

Cleaning your throttle body should take care of both problems. Clean your throttle body with throttle body cleaner. First disconnect the battery, clean the TB with TB cleaner, must be nice and shiny. When finished, hook the battery back up and drive around for 20 minutes or so with all accessories off, so the computer will relearn a properly functioning throttle body.

Your computer learned some bad habits, so when you changed the battery, the computer thought the throttle body was clean and functioning properly. So when you changed it, this caused all your problems. Very common, keep your throttle body clean, should be done at least once a year. Total cost if you do it yourself is around $5, for the can of TB cleaner.

Have a 04 chevy trailblazer changed the map sensor due to code, it come back got it changed out again and it still wants to throw same code, not alot but seen more after when tring to use defrost or...

Try cleaning the throttle body, a build up of grime on the throttle plate and surrounding area will cause a lean mixture to occur. Make sure you disconnect the battery for about 30 minutes while doing the cleaning procedure. This will force the computer to relearn to a clean throttle body. BTW, the fault codes only identify problem areas not specific parts, additional troubleshooting needs to be done after a code is read.
