Is there about 5 V?

YES -Go to step 79.

NO -Go to step 75.

75. Disconnect the connector from each of these sensors, one at a time, while measuring voltage between

body ground and ECM/PCM connector terminal A21 with the ignition switch ON (II).

Is there continuity?

YES -Repair short in the wire between the ECM/PCM (A21) and the MAP sensor or the output shaft
(countershaft) speed sensor, APP sensor A.

NO -Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM
(see UPDATING THE ECM/PCM ), or substitute a known-good ECM/PCM (see SUBSTITUTING
THE ECM/PCM ), then recheck. If the symptom/indication goes away with a known-good ECM/PCM,
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ).

79. Measure voltage between body ground and ECM/PCM connector terminal A20.

80. Turn the ignition switch OFF.

81. Disconnect the connector from each of these sensors, one at a time, while measuring voltage between

body ground and ECM/PCM connector terminal A20 with the ignition switch ON (II).

YES -Repair short in the wire between the ECM/PCM (A20) and the APP sensor B or the input shaft
(mainshaft) speed sensor.

NO -Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ),
or substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the
symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM (see
ECM/PCM REPLACEMENT ).

85. Measure voltage between body ground and ECM/PCM connector terminal E5.

Is there about 5 V?

YES -Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ),
or substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the
symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM (see

NO -Go to step 86.

86. Turn the ignition switch OFF.

87. Disconnect the FTP sensor 3P connector, then measure voltage between body ground and ECM/PCM

connector terminal E5 with the ignition switch ON (II).
