DTC P2176

DESCRIPTION AND OPERATION

The TAC system sets DTC P2176 when the ECM determines
the zero position of the throttle plate has not been successfully
learned.

At power up, the ECM adjusts the throttle plate to the limp-
home position, then begins to move the throttle plate closed.
The ECM monitors and verifies the amount of movement that
occurred. The throttle plate minimum position is held briefly
then verified against the expected minimum and maximum
range of throttle. If the zero position is found within range, then
the position is stored.

If the ECM is not able to learn the minimum position or if the
learning fails four consecutive ignition cycles, the ECM initiates
DTC P2176. Refer to

NO ECM POWER

DESCRIPTION AND OPERATION

Constant power is supplied to the ECM through terminal 71.
The ECM turns on when power is applied to terminal 72 of
connector [78]. The ECM goes through an initialization
sequence every time power is removed and re-applied to ter-
minal 72. The only visible part of this sequence is the check
engine lamp. Upon starting, the check engine lamp will illu-

minate for 4 seconds and then (if parameters are normal) go
out.

If battery power is absent at ECM terminal 71:

•

DTCs cannot be cleared. Tool will show them as cleared
but will be present next time ignition key is cycled.

•

ECM cannot be re-flashed.

STARTS, THEN STALLS

DESCRIPTION AND OPERATION

The starts, then stalls condition may be created by the fuel
system, the idle air control system or an ECM failure. When
this condition exists, see

There may be DTCs set causing this condition. Solve the
problems with the DTCs before performing the tests in this
section. The DTCs that may be involved with starts, then stalls
are:

•

Fuel injectors: DTCs P0261, P0262, P0263 and P0264

•

Ignition coils: DTCs P1351, P1352, P1354 and P1355

•

Lost idle: DTC P0505

•

TPS: DTCs P0122 and P0123

•

Password Problem: DTCs P1009 and P1010

•

JSS: DTCs P1501, P1502 and P1503

•

Neutral switch: DTC P1155

•

All modes: DTCs P0603 and P0605

Diagnostic Tips

•

The vehicle will stall on HDI models if the jiffy stand is
extended when the transmission is in gear and the clutch
is released.

•

If serial data is shorted, U1300 and U1301 will automatic-
ally set the check engine light.

•

DTCs P1009 and P1010 may accompany DTCs U1300
and U1301.

•

If this condition is fuel related, perform Fuel Pressure Test.
See the service manual.

•

If the fuel system passes the pressure test, perform the
Fuel System Electrical Test. See

6.36 FUEL SYSTEM

ELECTRICAL TEST

to jiffy stand tab (0.18 in (4.5 mm). If sensor is
mounted correctly, replace JSS. See the service
manual.

No.

3. Neutral Switch Test

Is neutral switch circuit operating normally?

Yes. Replace TSM/TSSM/HFSM. See the service
manual.

No. Replace neutral switch. See the service manual.

4. Fuel System Test

Perform Fuel Pressure test. See the service manual.

Is fuel pressure normal?

Yes. If fuel injectors are okay, replace ECM. See the
service manual.

manual.

2011 Touring Diagnostics: Engine Management 6-105

FUEL SYSTEM ELECTRICAL TEST

DESCRIPTION AND OPERATION

With the IGN ON and the engine stop switch at RUN, the ECM
will energize the system relay to complete the circuit to the in-
tank fuel pump. It will remain on as long as the engine is
cranking or running and the ECM is receiving ignition reference
pulses from the CKP sensor. If there are no reference pulses,
the ECM will de-energize the system relay within 2 seconds
after ignition is turned on or the engine has stalled, or immedi-
ately after the ignition is shut off.

The fuel pump delivers fuel to the injectors. The pressure reg-
ulator controls system pressure.

See

Figure 6-48

. When the engine is stopped, the pump can

be turned on by applying battery voltage to the (O/GY) wire
and ground to the (BK) wire of the fuel pump connector [141B].

Improper fuel system pressure may contribute to the following
symptoms:

•

Engine cranks, but will not run.

•

Engine cuts out (may feel like ignition problems).

•

Hesitation, loss of power and poor fuel economy.

NOTE

After turning ignition off, wait 10 seconds before turning the
ignition back on to get the fuel pump to reprime. This time-out
period is necessary for the fuel pump and IAC to reset.

MISFIRE AT IDLE OR UNDER LOAD

DESCRIPTION AND OPERATION

Misfire conditions may be caused by:

•

Battery condition and connections.

•

Fuel system problems. Refer to

Table 6-1

Table 6-2

and

Table 6-3

•

Ignition system faults.

Diagnostic Tips

Wipe up spilled fuel and dispose of rags in a suitable
manner. An open spark around gasoline could cause a
fire or explosion, resulting in death or serious injury.
(00518b)

When performing the steps in the diagnostic tests, a known
good part can be used to verify whether a suspected part is
faulty. The ignition coil does not require full installation to be
functional. Verify faulty ignition coil by performing resistance
test. See

ed02012

Figure 6-50. Spark Tester

IN-LINE SPARK TESTER

TOOL NAME

PART NUMBER

SNAP-ON IN-LINE SPARK TESTER

YA840

See

Figure 6-51

. The use of a SNAP-ON IN-LINE SPARK

TESTER (Part No. YA840) or equivalent can help determine

whether a problem exists in the ignition or fuel systems. If the
test light flashes without interruption on both cylinders during
the misfire event, verify spark plug condition and gap and
inspect the fuel system for proper operation. If the test light
does not flash, or the flash is interrupted during the misfire
event, the problem is ignition related.

Turn IGN OFF.

Remove front spark plug wire and install SNAP-ON IN-
LINE SPARK TESTER (Part No. YA840) between spark
plug wire and spark plug.

Start engine and inspect tester light. The light will flash on
each spark event if power is transmitted to the plug.

Install and repeat procedure on rear cylinder.

NOTE

A SNAP-ON IN-LINE SPARK TESTER (Part No. YA840) can
also be used in conjunction with a load applying dynamometer
to diagnose misfire under load.
