What do you need to know about boost sensor?
A boost pressure sensor is a part of a turbocharged engine that measures and regulates the air pressure and controls the boost. Here are the most common symptoms. Ask a mechanic
When does a boost pressure sensor go bad?
This code is triggered when the Engine Control Module (ECM) detects that the boost pressure sensor does not match the specification as the manifold pressure sensor (MAP) or the barometric pressure sensor (BARO) when the engine is idle.
What happens when the turbo boost sensor is damaged?
The turbo boost pressure sensor is damaged and responding relatively slower to changing pressure. When the P0236 code is triggered, the PCM reacts by entering into an engine management failure mode, as it ignores the real manifold pressure reading and assumes another reading, limiting the engine capability.
What to do if your ECM has a bad boost sensor?
Remove and replace the boost sensor if it is providing the ECM with an incorrect pressure reading. Check the hoses and connections to the turbo boost sensor and see if they are clogged or have any blockages. In that case, cleaning these connections will solve the problem.

How does a turbo boost work on a car?
The boost pressure sensors, MAP sensors and throttle position work together to make sure the desired pressure matches actual pressures. If the ECM sees a large enough variance in the boost requested and the boost measured, a code will be set. The code could have the wastegate, diverter valve or sensor listed in the description.
How does a boost pressure sensor work on a supercharged engine?
Boost pressure sensors control the boost level produced in the intake manifold of a turbocharged or supercharged engine. They affect the air pressure delivered to the pneumatic and mechanical wastegate actuator. Fig. 1 shows a typical boost pressure sensor. Fig. 1 The boost pressure sensor measures the absolute pressure before the throttle valve.
How does a turbo boost pressure sensor work?
When the intake manifold pressure is high due to turbo boost, sensor voltage output is 2.0-4.7 volts. The sensor receives a 5-volts reference from the ECM. Sensor ground is also provides by the ECM. The ECM uses boost pressure combined with intake air temerature to determine the volume of air enter- ing the engine (Fig. 2).
Can a turbo MAP sensor work on a na?
NA and turbo map sensors have opposite pin locations on the sensor. nA harness needs to have plug wiring reversed to work with a turbo map sensor. Luke you can use an fg turbo map sensor as a straight plugin on the na wiring and no pins need to be moved. You can turn off the boost sensor so you don’t have the idle and coast issues.
Where is the MAP sensor on a Chevy?
The MAP sensor is the sensor that reads boost- Manifold Absolute/Air Pressure sensor is what it is. It is located on the intake runner on the 01 engines, but is in the neck of the bridge on 02-04 engines. The sensor on the bracket in your picture is the barometric pressure sensor, it measures the outside air pressure.
What causes a bad turbo boost pressure sensor?
The boost pressure sensor is clogged or contaminated with dirt and debris. The turbo boost pressure sensor is damaged and responding relatively slower to changing pressure.
Why does the p0236 code appear on the boost sensor?
This code is triggered when the Engine Control Module (ECM) detects that the boost pressure sensor does not match the specification as the manifold pressure sensor (MAP) or the barometric pressure sensor (BARO) when the engine is idle. Why Does the P0236 Code Appear? There are several reasons why the P0236 code is triggered.
What to do if your boost sensor is leaking?
Check boost leak symptoms. There are several ways to fix the P0236 code and the best way is to take the car for an inspection to an authorized dealer. The auto-specialist will use an advanced scanner to identify the problem and it will be easier to fix it. Besides that, here are the two common troubleshooting techniques you can try.

How do you remove a boost pressure sensor?
REMOVAL (1) Disconnect the negative battery cable. (2) Unplug the electrical connector. (3) Remove the sensor retaining bolts, remove the sensor and O-ring. INSTALLATION (1) Inspect boost pressure sensor O-ring for cuts or abrasions, replace as necessary.
What is the voltage of the turbo boost sensor?
When the intake manifold pressure is high due to turbo boost, sensor voltage output is 2.0-4.7 volts. The sensor receives a 5-volts reference from the ECM.
