8. SC499
Excerpt from RTB #RD074077a
False procedure carried out to clean the ITB speed sensor could cause SC499-40.
Following are important notes on the correct procedure.
1. Use a vacuum cleaner or an air blower to remove dust.
2. Wipe the sensors with a wet cotton swab. If a cotton swab is not at hand, wipe
the sensors with a wet cloth. Use water if necessary, but DO NOT use solvent of
any type (ethanol, etc).
Note:
DO NOT scrub with force or cover the tip of a screwdriver with cloth to clean the sensors.
Doing so could scrape off the coated surface and disable proper detection as the surface
of the sensor is coated with slits that correspond to the slits on the ITB.
Sealing of the ITB speed sensor was modified to prevent dust from getting inside
the sensor. (P/N of the new ITB speed sensor: D0746208)
