2003 Grand Marquis digital speedo only reads "0". All other displays read correctly. Could it be the speed control? If so, where exactly is it located?

The speedometer provides speed information based on a speed/distance pulse signal from the vehicle speed sensor (VSS). The VSS is mounted on the speedometer driven gear in the transmission.
or the gauge is bad .
  • The speedometer/odometer is inoperative
  • CJB fuse 14 (10A).
  • Vehicle speed sensor (VSS).
  • Circuitry.
  • Instrument cluster.
  • Go To Pinpoint Test E .
PINPOINT TEST E: THE SPEEDOMETER/ODOMETER IS INOPERATIVE CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.
VSS C1088
Raise the drive wheels off the ground. While rotating the driveshaft, measure the AC voltage between the VSS C1088 pin 1, circuit 679 (GY/BK), component side and the VSS C1088 pin 2, circuit 676 (PK/OG), component side.
  • Is the voltage between 1.3 volts AC to 6.1 volts AC?
Yes GO to E2 .

No CHECK and INSPECT the speedometer drive gear. INSTALL a new VSS if the speedometer drive gear is OK. TEST the system for normal operation E2 CHECK CIRCUIT 679 (GY/BK) AND CIRCUIT 676 (PK/OG) BETWEEN THE INSTRUMENT CLUSTER AND THE VSS

What does error 90 Mean on an Electrolux Ewf 1087

E90 is family error code visible to the customers. It is necessary to read the error in the service mode so please proceed with the following procedure for rapid reading of alarm codes:
Press and hold down START/PAUSE and the option button nearest to the START/PAUSE button for at least two seconds!
After that the display will show one of the following errors that are more precise:
E91, E92 - Communication incongruence between main board and display board (versions not compatible). Posible causes: wirings, main board or control/disply board.
E93 - Incorrect configuration of appliance. Posible causes: Incorrect configuration data; electronic board faulty.
E94 - Incorrect configuration of washing cycle.
Posible causes: Incorrect configuration data; electronic board faulty.
E95 - Communication error between microprocessor and
EEPROM. Posible causes: Electronic board faulty.
E97 - Incongruence between programme selector and
cycle configuration. Posible causes: Faulty electronic board (Wrong configuration data).
Considering that this is a complicated fault, my advice is to contact an authorized service center.They have special equipment such as an interface that allows them to upgrade software in your appliance. If you are not doing anything on the appliance before the failure, the only thing you can check is the contacts between wiring and electronics.

Why will be incorrect grammer to say hair that turns heads?

Your question should read "Why would it be incorrect grammar to say "hair that turns heads"." It would not be incorrect grammar for a sign or motto, but it not a complete sentence. A correct sentence would be "She has hair that turns heads", or "hair that turns heads is sometimes on fire."

Fxdx drops out of first gear and a false advance between 2 and 3

Hi Anonymous, setting up a transmission should be left to a professional, you obviously had an engagement issue which could have been caused by a misadjusted shifter pawl, faulty shifter cam, spacing issue and it's too bad you can't find the very first and best tool you ever bought for your Harley Davidson. Despair not, for a mere $6.50 you may be able to download another one from the website below and good luck. Harley Davidson Manuals Mark Workshop
