DTC Advanced Diagnostics: P0236
DTC P0236:Turbocharger Boost Sensor Circuit Range/Performance Problem

General Description

The powertrain control module (PCM) monitors the pressure signal of the turbocharger boost sensor. During the range check, the turbocharger booster sensor will be monitored if it is within a physically possible range. If the turbocharger boost sensor output pressure is a specified value, the PCM detects a malfunction and stores a DTC.

Malfunction Threshold
Continuous check
The turbocharger boost sensor output pressure is greater than 406.297 kPa (3,047.48 mmHg, 119.9795 inHg), or less than 30 kPa (225 mmHg, 8.8 inHg).
Check in post drive
The turbocharger boost sensor output pressure is greater than 511.992 kPa (3,840.25 mmHg, 151.1912 inHg).

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
Turbocharger boost sensor failure

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
