Codes P0700(70-3) and P1887(53-1)

Hi,

My Honda airwave the D light on the dashboard blinks when the car is driven, and the handbrake lights stay on permanently as well but no abs light. The D light keeps blinking irrespective of the gear the car is in until the ignition is switched off and on again. However, it resumes blinking as soon as I accelerate past 35 - 40 km/hr.

In the morning when I start the car, the RPM shoots up normally to 1,500-1,800 RPMs and starts coming down gradually. When I engage the reverse gear to back out, RPMs drop to about 500 when I completely break. When I then try to switch from R to D, RPM shoots up to 1500 before settling back down to about 800. When this happens, there is a small delay (about a second) before the vehicle starts moving forward. At this point the D light doesn't blink until I accelerate to about 30-40km/hr.

My mileage consumption in the city sucks a bit (9km/L). My mechanic says it's my ABS module, another says it's an electrical fault. Yet another said it doesn't matter since my check engine light is not on. Anyone had this type of issue and how was it resolved? Waiting for your informed answers. Thanks.
