Narrative:

During takeoff at approximately 90 KTS, the master caution light and engine annunciation light illuminated. We aborted the takeoff without further incident. I elected to return to the gate as a precautionary measure, allowing the brakes and tires to cool and be inspected. Maintenance did a check and determined that the pitot switches were off. During the after start checklist, I interpreted the probe heat lights for the engine anti-ice lights which were on for the icing conditions. Other contributing factors were the reduced visibility which required increased vigilance outside the aircraft during taxi.

Title: B737 FLT CREW ABORTS TKOF AFTER RECEIVING MASTER CAUTION AND ENG WARNING LIGHTS. AFTER MAINT REVIEW, FLT CREW FAILED TO INSURE THE PITOT HEAT WAS TURNED ON.

Narrative: DURING TKOF AT APPROX 90 KTS, THE MASTER CAUTION LIGHT AND ENG ANNUNCIATION LIGHT ILLUMINATED. WE ABORTED THE TKOF WITHOUT FURTHER INCIDENT. I ELECTED TO RETURN TO THE GATE AS A PRECAUTIONARY MEASURE, ALLOWING THE BRAKES AND TIRES TO COOL AND BE INSPECTED. MAINT DID A CHK AND DETERMINED THAT THE PITOT SWITCHES WERE OFF. DURING THE AFTER START CHKLIST, I INTERPED THE PROBE HEAT LIGHTS FOR THE ENG ANTI-ICE LIGHTS WHICH WERE ON FOR THE ICING CONDITIONS. OTHER CONTRIBUTING FACTORS WERE THE REDUCED VISIBILITY WHICH REQUIRED INCREASED VIGILANCE OUTSIDE THE ACFT DURING TAXI.
