To t2erns, thanks for the info. pardon me but what is this tsb? My unit is a second hand car. Can I just brought it to any Honda casa for them to check? I'm afraid the cost of repair in casa will be high that's why I'm looking for an alternative shop. Anyway, I'll try to bring my car there and have check and estimate the cost first. Thanks.

To speedyfix, thanks for your help also but do you idea how much and where to buy this sending unit? Also do you know any shop who can do this work? Thanks!
