Road Test "D" Range: Testing

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 1994 Mazda MX-5 Miata, 1992 Mazda MX-5 Miata, 1992 Mazda MPV, 1992 Mazda B2200, and 1991 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.

Perform TESTING PREPARATION PROCEDURES. Connect vacuum gauge, PCMT tester, tachometer and pressure gauges to vehicle.

NOTE: For complete PCMT tester information, see SELF-DIAGNOSIS (1994 MIATA ONLY).
  1. Shift to "D" while in NORMAL mode and OD OFF switch in released position. Accelerate vehicle at half and full throttle valve opening. Throttle sensor voltage on PCMT tester (if used) represents throttle valve opening. Vacuum on other testers represents throttle opening.
  2. Ensure "1"-"2", "2"-"3" and "3"-OD upshifts, downshifts and lock-up are obtained. Use same procedure to check upshift for shift shock. Drive in OD, shift to "S" to check OD-"3" downshift and release throttle to check for engine braking in 3rd and 2nd.
  3. Select "D" while in HOLD mode. Accelerate vehicle, check "2"-"3" upshift and downshift and for no 1st and OD. Check shift points, see appropriate SHIFT SPEED CHARTS.
  4. Drive in 3rd and 4th gear to ensure no unusual noise or vibration is heard. Check torque converter, axle shafts and differential for source of unusual noise. Ensure kickdown operates properly and shift points match appropriate SHIFT SPEED CHARTS.
