Are DTCs present for two or more sensors
connected to PCM terminal 2H?
Sensor connected to PCM terminal 2H:
•
IAT sensor (P0112, P0113)
•
FHO2S (P0131, P0132)
•
RHO2S (P0138)
•
Barometric pressure sensor (P2228, P2229)
•
Manifold absolute pressure sensor (P0107,
P0108)
•
ECT sensor (P0117, P0118)
•
TP sensor (P0122, P0123)
•
TR switch (P0707, P0708)
•
TFT sensor (P0712, P0713)
Yes
Go to next step.
No
Repair open GND circuit to sensor where constant
voltage circuit inspection failed.
10
Turn ignition switch off.
Disconnect WDS or equivalent from DLC-2.
Disconnect PCM connector.
Measure resistance between GND circuit at
appropriate sensor connector and PCM
connector terminal 2H.
Is resistance
less than 5.0 ohms
?
Yes
Reconnect sensor connector.
Go to appropriate DTC test.
No
Repair open GND circuit.
11
Turn ignition switch off.
Disconnect PCM connector.
Measure resistance between battery negative
terminal and PCM terminals 4X, 2AB, and 2AC.
Is each resistance
less than 5.0 ohms
?
Yes
Go to next step.
No
Repair open GND circuit.
12
Turn ignition switch off.
Measure resistance between GND circuit at
following sensor connector and GND:
•
IAT sensor (integated in MAF sensor)
•
FHO2S
•
RHO2S
•
Barometric pressure sensor
•
Manifold absolute pressure sensor
•
ECT sensor
•
TP sensor
•
TR switch
•
TFT sensor
Yes
GND circuits are okay.
Inspect for constant voltage at suspect sensor
connector again.
No
Inspect for open GND circuit.
13
Turn ignition switch off.
Disconnect TP sensor and PCM connectors.
Turn ignition switch to ON position.
Measure voltage between constant voltage
circuit at TP sensor connector and battery
negative terminal.
Is voltage
less than 0.5 V
?
Yes
Inspect for constant voltage at suspect sensor
connector again.
No
Repair constant voltage circuit shorted to power in
harness.
14
Verify test results.
•
If okay, return to diagnostic index to service any additional symptoms.
•
If malfunction remains, replace PCM.
