What causes the P0106 code?
The MAP circuit for range and performance problem may have several causes:
What are the symptoms of the P0106 code?
P0106 code will be generally preceded by the Check Engine Light coming on the dashboard display. The vehicle in most cases will not run well, idle poorly, accelerate erratically, run rich, and backfire because the MAP sensor and throttle position sensor will not operate together properly.
How does a mechanic diagnose the P0106 code?
P0106 is diagnosed with an OBD- II scanner. A qualified technician should then reset the OBD- II fault codes and perform a road test of the vehicle to see if the code comes back. He can observe this by watching live data streaming on his scanner while driving. If the code comes back, then the mechanic will need to do a close inspection to see if the vacuum line and other hoses on the intake system are missing, loose, damaged, or disconnected. If these things appear to be correct, the technician should do a voltage output test on the sensor while the engine is running to determine if the output voltages fluctuate with engine speed and load on the engine. Check that all grounds are operating correctly, since any ground related to the ECU could cause signal fluctuations from sensors.
Common mistakes when diagnosing the P0106 code.
Diagnostic errors are largely due to not following the proper procedure. First, follow the test procedure in the diagnosis to insure there is no intake air leak like a bad vacuum hose or connection. The technician must verify that the voltage output of the MAP sensor is correct and fluctuates with the engine speed and proper voltage. Idle voltage is normally 1 to 1.5 volts and full throttle is usually around 4.5 volts.
Do not buy a new MAP Sensor or ECU unless it is clearly at fault.

Very simple. Disconnect the plug from it, unscrew, replace with new sensor and o-ring.....2 screws hold it on.

There is a special socket for O2 sensors which allow the wires to stick out and not get twisted up. It's not expensive and available at most auto parts stores. Disconnect the sensor from the wiring harness, with the plug and then use the socket to remove and replace the new sensor. Re-connect electrical plug.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- No throttle response
Possible Causes
- Harness or connector (The TP sensor circuit is open or shorted.)
- Electric Throttle Control Actuator (or Throttle Body Motor)
- Accelerator Pedal Position Sensor (APP)
P0220 Description
Electric Throttle Control Actuator consists of throttle control motor,
throttle position (TP)sensor, etc. The throttle position sensor responds
to the throttle valve movement.
The throttle position sensor
has the two sensors. These sensors are a kind of potentiometers which
transform the throttle valve position into output voltage, and emit the
voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
When is the code detected?
An unexpected voltage from the TP sensor is sent to ECM.

You may have actually had a faulty MAP that needed replace. Thing is that any time you get a "check engine", the cruise will be disabled. you must clear the code, by either a trouble code diagnostic tool, or disconnect the battery for about five minutes. Codes will clear, and cruise will start working again.

Hi, I have a 2001 polo 1.4 mpi it lackes power when you hit a hill it just dies, It has had new cat, fuel filter, fuel pump and throttle body, but is still the same it just dose not want to give me full rev's?
?€¢
The barometric pressure (BARO)
?€¢
The manifold absolute pressure (MAP)
?€¢
The intake air temperature (IAT)
?€¢
The engine RPM
P0121
The predicted air flow and the predicted MAP combined are outside a calibrated range for more than 3 seconds.
Circuit/System Testing
?€¢
Inspect thoroughly for any type of leak or restriction
?€¢
Air leaks at throttle body mounting area and intake manifold sealing surfaces
?€¢
Throttle body for dirt, debris, and coking--Refer to Throttle Body Cleaning.
?€¢
Increase the engine speed slowly to 3,000 RPM, then back to idle.
?€¢
Exit from the snapshot and review the data.
?€¢
Observe the Mass Air Flow (MAF) Sensor parameter frame by frame with a scan tool. The MAF sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.
?‡'
If the MAF sensor g/s does not change smoothly and gradually as the engine speed is increased and is returned to idle, refer to DTC P0101 or P1101.
?€¢
Broken throttle shaft
?€¢
Any throttle body damage
?‡'
If any of these conditions exist, replace the throttle body assembly.
