DTC P0 191 FUEL RAIL PRESSURE SENSOR CIRCUIT
RANGE/PERFORMANCE
CIRCUIT DESCRIPTION
Refer to DTC P0087 on page 05 −314.
INSPECTION PROCEDURE
HINT:
S If DTCs P0087, P0 190, P0 192, and P0 193 are output simultaneously, the manifold absolute pressure
sensor circuit may be open or short. Perform troubleshooting for those DTCs first.
S Read freeze frame data using the hand −held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, 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.

DATA LIST/ACTIVE TEST
1. DATA LIST
HINT:
Using the hand−held tester DATA LIST allows switch, sensor, actuator and other item values to be read with-
out removing any parts. Reading DATA LIST early in troubleshooting is one way to shorten labor time.
NOTICE:
In the table below, the values listed under ”Normal Condition” are reference values. Do not depend
solely on these reference values when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch to OFF.
(c) Connect the hand−held tester to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the hand−held tester ON.
(f) Enter the following menus: DIAGNOSIS / OBD/MOBD / DATA LIST.
(g) According to the display on the tester, read DATA LIST.

17 INSPECT ENGINE COOLANT TEMPERATURE SENSOR
(a) Remove the engine coolant temperature sensor.
(b) Measure the resistance between the terminals.
Standard:
2.32 to 2.59 k
at 20_C (68_F)
0.310 to 0.326 k
at 80_C(176_F)
NOTICE:
If you check the engine coolant temperature sensor in wa-
ter, be careful not to allow water to contact the terminals.
After checking, dry the sensor.
HINT:
Alternate procedure: Connect an ohmmeter to the installed en-
gine coolant temperature sensor and read the resistance. Use
an infrared thermometer to measure the engine temperature in
the immediate vicinity of the sensor. Compare these values to
the resistance/temperature graph. Change the engine temper-
ature (warm up or allow to cool down) and repeat the test.
(c) Reinstall the engine coolant temperature sensor.
