Steps to execute SP2920 were added in the revision.
Reason: SP2920-001 is needed to initialize the position of the ITB after its replacement and
cleaning/replacement of the feedback sensor.
This RTB has been issued to announce the important notes on cleaning the ITB speed
sensor to prevent SC499-40 as a result of carrying out cleaning incorrectly.
The following procedure is recommended when cleaning the two ITB speed sensors
indicated in yellow in the photo below:
1. Use a vacuum cleaner or an air blower to remove dust.
2. Wipe the sensors with a wet cotton swab. If a cotton swap 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 apply cloth to the tip of a screwdriver when cleaning the
sensors. Doing so could scrape off the coated surface and disable proper detection
because the surface of the sensor is coated with slits that correspond to the slits on the
ITB.
The ITB speed sensor was modified to prevent dust from getting inside the sensor by
improving the sealing. (P/N of the new ITB speed sensor: D0746208)
