---|---|---|---|---|---|
P010515 | Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Battery or Open |
The E.F.I. vacuum sensor assembly output voltage is higher than 4.5 V for 0.5 seconds or more (1 trip detection logic). |

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) |
|
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 E.F.I. vacuum sensor assembly voltage and uses this value to calculate the intake manifold pressure. When the E.F.I. vacuum sensor assembly output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the E.F.I. vacuum sensor assembly circuit, illuminates the MIL and stores a DTC.
Example:
If the E.F.I. vacuum sensor assembly output voltage is higher than 4.5 V for 0.5 seconds or more, the ECM stores this DTC.

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
1. |
CHECK HARNESS AND CONNECTOR |
*a | Front view of wire harness connector (to E.F.I. Vacuum Sensor Assembly) |
HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
(a) Disconnect the E.F.I. vacuum sensor assembly connector.
(b) Turn the ignition switch to ON.
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition |
Specified Condition |
---|---|---|
C21-3 (VC) - C21-1 (E2) |
Ignition switch ON | 4.75 to 5.25 V |
C21-2 (PIM) - C21-1 (E2) |
Ignition switch ON | 1.2 to 5.25 V |
(d) Turn the ignition switch off and wait for at least 30 seconds.
(e) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
---|---|---|
C21-1 (E2) - Body ground |
Ignition switch off | Below 1 Ω |
C21-3 (VC) - C21-2 (PIM) |
Ignition switch off | 171 to 189 kΩ |
OK | REPLACE E.F.I. VACUUM SENSOR ASSEMBLY |
|
2. |
CHECK HARNESS AND CONNECTOR (E.F.I. VACUUM SENSOR ASSEMBLY - ECM) |
(a) Disconnect the E.F.I. vacuum sensor assembly connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
---|---|---|
C21-1 (E2) - C139-119 (EPIM) |
Always | Below 1 Ω |
C21-2 (PIM) - C139-120 (PIM) |
Always | Below 1 Ω |
C21-2 (PIM) or C139-120 (PIM) - Other terminals |
Always | 10 kΩ or higher |
OK | REPLACE ECM |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR |
