M20D-FKS ENGINE CONTROL SFI SYSTEM P010515 Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Battery or Open
DESCRIPTION
Refer to DTC P010511.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P010515 | Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Battery or Open | The manifold absolute pressure sensor output voltage is higher than 4.5 V for 0.5 seconds or more (1 trip detection logic). | ·
Open or short in manifold absolute pressure sensor circuit ·
Manifold absolute pressure sensor ·

Comes on | DTC stored | SAE: P0108 |
- HINT:
-
When a DTC is output, check the Data List item "Intake Manifold Absolute Pressure" using the GTS.
DTC No. Intake Manifold Absolute Pressure Malfunction P010515 Higher than 130 kPa (18.85 psi) ·Short in VCPM to PIM circuit
·Open in PIM circuit
·Open in EPIM circuit
-
If the Data List displays a normal value, the normal value may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
MONITOR DESCRIPTION
The ECM monitors the manifold absolute pressure sensor voltage and uses this value to calculate the intake manifold pressure. When the manifold absolute pressure sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the manifold absolute pressure sensor circuit, illuminates the MIL and stores a DTC.
Example:
If the manifold absolute pressure sensor output voltage is higher than 4.5 V for 0.5 seconds or more, the ECM stores this DTC.

CONFIRMATION DRIVING PATTERN
- HINT:
- ·
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
·When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Start the engine and wait 5 seconds or more [A].
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes [B].
Read the pending DTCs.
- HINT:
- ·
If a pending DTC is output, the system is malfunctioning.
·If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P010515.
Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL | ·
DTC judgment completed ·
System normal |
| ABNORMAL | ·
DTC judgment completed ·
System abnormal |
| INCOMPLETE | ·
DTC judgment not completed ·
Perform driving pattern after confirming DTC enabling conditions |
- HINT:
- ·
If the judgment result is NORMAL, the system is normal.
·If the judgment result is ABNORMAL, the system is malfunctioning.
·[A] to [B]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
·When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
WIRING DIAGRAM
Refer to DTC P010511.
CAUTION / NOTICE / HINT
- HINT:
-
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE

(to Manifold Absolute Pressure Sensor) |
- HINT:
-
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
Disconnect the manifold absolute pressure sensor connector.
Turn the ignition switch to ON.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Switch Condition Specified Condition C16-3 (VC) - C16-1 (E2) Ignition switch ON 4.5 to 5.5 V C16-2 (PIM) - C16-1 (E2) Ignition switch ON 1.2 to 5.25 V
Turn the ignition switch off and wait for at least 30 seconds.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Switch Condition Specified Condition C16-1 (E2) - Body ground Ignition switch off Below 1 Ω C16-3 (VC) - C16-2 (PIM) Ignition switch off 171 to 189 kΩ
- Result:
Proceed to OK NG
OK
