DTC P0236-00: Boost Pressure Sensor Circuit Range/Performance Problem (H3T)
P0236: 00 (PCM (H3T)) DETECTION CONDITION AND POSSIBLE CAUSE
| System malfunction location |
Boost pressure sensor circuit range/performance problem |
| Detection condition |
Determination condition
- Any one of the following conditions is met:
- The condition has continued in which difference in barometric pressure measured and turbocharger/supercharger boost pressure is standard or more, difference in manifold absolute pressure and turbocharger/supercharger boost pressure is standard or more and difference in turbocharger/supercharger boost pressure and exhaust pressure is standard or less.
- The condition has continued in which difference in barometric pressure measured and turbocharger/supercharger boost pressure is standard or less, difference in manifold absolute pressure and turbocharger/supercharger boost pressure is standard or less and difference in turbocharger/supercharger boost pressure and exhaust pressure is standard or more.
Precondition
- Ignition switched off: 12.0-15.0 min have elapsed
- The following DTCs are not detected:
- BARO sensor: P2228: 00 and P2229: 00
- MAP sensor: P0107: 00 and P0108: 00
- Boost pressure sensor: P0237: 00 and P0238: 00
- GPF pressure sensor: P0472: 00 and P0473: 00

| Vehicle status when DTCs are output |
|
| Repeatability verification procedure |
- Clear the DTC recorded in the memory. (See CLEARING DTC
.)
- Start the engine. (Engine cold)
- Drive the vehicle on fl at roads under the following conditions 10 times.
- Start the engine. (Engine cold)
- Drive the vehicle on a flat road surface 10 times under the following conditions.
|
| Inspection/action procedure |
- Proceed with the inspection/action in the order from Step 1 below.
- After part repair or replacement, perform the repeatability verification procedure and perform a DTC inspection. (See DTC INSPECTION
)
- If the DTC inspection indicates the same DTC again, go to the next step.
- Inspect the boost pressure sensor connectors and terminals.
Purpose/reason (possible cause)
Boost pressure sensor connector or terminal malfunction
Referred to workshop manual item
See CONNECTOR INSPECTION
- Inspect the boost pressure sensor.
Purpose/reason (possible cause)
Boost pressure sensor malfunction
Referred to workshop manual item
(See BOOST PRESSURE SENSOR INSPECTION
.)
- Inspect the PCM connectors and terminals.
Purpose/reason (possible cause)
PCM connector or terminal malfunction
Referred to workshop manual item
(See CONNECTOR INSPECTION
)
- Replace the PCM.
Purpose/reason (possible cause)
PCM malfunction (no other possible malfunction considered)
Referred to workshop manual item
(See PCM REMOVAL/INSTALLATION [H3T]
)
