Your emergency brake is a mechanical brake system that is indipendant of the regular hydrolic system. If the red brake light on the dash is on make sure it's the emerg. brake and not a problem with the fluid level or the calapers sticking. the best way to check the emerg. brake is to rase both rear wheels off the ground and spin them. If they spin, the emerg. brake is not locked up. If they don't spin, take the rear tires off and the brake drums. (you may have rear disk brakes.) check the springs to insure they are all hooked up properly. If there is no problem there, follow the parking brake cable to check for damage. The cable is like a brake cable on a bike, If the inner cable is binding inside the cable sleeve,the brake wont release. If you have rear disc, it's probly a bad calaper.The park brake cable is attached to the calapers. Rember if it wont run it's annoying but if it won't stop, it's deadly. DON"T experiment with brakes!!! If in doubt, take it to a pro.

VTEC Oil Pressure Switch Circuit High Voltage - With Automatic Transmission
Basicallly the sensor has gone bad or an oil passage has become blocked.
**. Locate the Variable Timing Electronic Control (VTEC) pressure switch on the end of the cylinder head. Honda has had problems with the VTEC oil pressure switch, there is an updated part number for the vehicle (37250-PNE-G01). On this vehicle the VTEC oil pressure switch can fail at any RPM.
2. The VTEC oil switch is normally closed, and grounds the reference voltage from the Engine Control Module (ECM) on the Blue/Black (BLU/BLK) wire. If the code sets at idle - 2500 RPM - and the Brown/Yellow wire has a good ground, then suspect a faulty VTEC oil pressure switch.
3. At approximately 2500-4000 RPM and when driving the vehicle, the VTEC system should turn on. To turn on the system, the ECM energizes the VTEC Solenoid valve and it allows oil pressure into the intake valve rocker arms, the oil pressure opens the VTEC oil pressure switch so the Engine Control Module (ECM) can verify that the VTEC did turn on correctly.
4. The code will set at idle to 2500 RPM if the reference voltage is not grounded. The code will set above 2500-4000 RPM if the VTEC oil switch does not open.
5. If the code sets at 2500-4000 RPM or higher, the problem can be a low oil level or pressure, or a malfunction in the VTEC assembly.
Potential Causes: Low Engine Oil
Plugged Oil Passage
Insufficient Oil Pressure
Plugged Oil Screen
Insufficient Oil Volume
Malfunctioning VTEC Oil Pressure Switch
Defective VTEC Solenoid
