Low power

Engine misfire
Aftertreatment performance complaints
Root Cause:
• Incorrect pressure/temperature sensor installed in the incorrect location on the
engine.
Verification
• Remove the pressure/temperature sensor in question and verify
pressure/temperature sensor part number.
• View pressure/temperature sensor values in a key on engine off condition using
INSITE® electronic service tool or equivalent, an incorrect pressure/temperature
sensor can give an incorrect value.
• At key ON engine off, the barometric air pressure should read the local barometric
air pressure, and the intake manifold pressure should read 0.0 in-hg.
Resolution
Refer to QuickServe Online parts catalog on to determine the correct sensor to use in the
correct location for a given engine.
Install correct pressure/temperature sensor. See Table 1 below for part numbers.

Part Number
Part Identification
• Pressure/temperature sensor part number is located on underside of
pressure/temperature sensor body.
• Pressure/temperature sensor must be removed to verify part number. See Figure 1
for part number location. See Figure 2 for pressure/temperature sensor similarity
examples.
