If, after installing your BBK 1763 ‘05+ throttle body, you experience a
FAILSAFE
mode or
CHECK ENGINE
light,
try the following procedure:
First be sure that the plastic capped spring is hooked into the gear and rotated approx 180° COUNTER-
CLOCKWISE until it pops into locked position.
If that is verified and correct and you are still having issues then follow the directions for checking TPS voltage.
CHECKING TPS VOLTAGE
To check the TPS voltage you must have a
DIGITAL
voltmeter.
1. Re-assemble and install the stock throttle body.
2.
LEAVE THE THROTTLE BODY MOTOR UNPLUGGED
(the small connector on the driver side of the throttle
body).
3. Ground the black wire of your meter and poke the probe of the red wire on the meter into the
YELLOW
wire
of the TPS sensor which is the bottom wire on the plug located on the passenger side of the throttle body. You
DO NOT
need to break the wire to read voltage. The best way to probe the yellow wire is to poke the probe into
the plastic harness plug (while it’s plugged in to the TPS). You will need to penetrate the blue insulator the goes
around the end of the yellow wire (hidden inside the harness plug) to reach the bare metal end of the yellow wire.
Touch the probe to the bare metal end of the yellow wire
4. Turn the ignition to the
ON
position but do not start the car.
5. Read the meter display. You should see a voltage reading between 1.19-1.31 volts. Write the voltage down.
6. Now re-install the BBK throttle body and repeat steps 2-5.
7. If the TPS voltage on the BBK throttle body varies from the stock TPS voltage then follow the next steps to
adjust the BBK to stock settings. This is easily done with the throttle body bolted to the car.
ADJUSTING TPS VOLTAGE
1.
With your meter still connected, loosen the mounting screws on the TPS sensor and gently rotate it until the
desired voltage is acheived, then tighten the screws.
Note; If desired voltage cannot be acheived, you will need to unbolt the TPS from the throttle body and remove the
alignment tab with a razor knife or grinder. Be sure to leave the tab area clean so the TPS will mount flush again.
Re-install the TPS and adjust the voltage.

.
Once the desired voltage is acheived, p
lug the throttle body motor in.
3
.
Turn
the
ignition key to the
O
FF
position
, then cycle the ignition key from
the O
N
position 4 times to allow the car to
"self
check
"
the throttle
body
and sensors
for proper operation.
If the throttle body
voltage and sensors are
correct then the CHECK ENGINE and FAILSAFE warnings should be gone when
you turn
the key on for the 4th time.
