1. HOW TO
DETERMINE THE
FAILED
TRANSMISSION
VACUUM
MODULATOR IN
CAR?

2. Vacuum modulator inside the car ensure
that the gear shift can be accomplished.

3. Defined as a load sensor in the engine to
calculate the amount of load placed in
it.

4. Once the amount is detected, it allows
the transmission to shift properly.

5. If the vacuum modulator becomes
defective, there are certain signs you
will notice.

6. Go through the signs to recognize the failed
transmission vacuum modulator in the car.

7. Failed vacuum modulator illuminates
the check engine light on the dashboard.
ILLUMINATED
CHECK ENGINE
LIGHT

8. If the modulator sends a wrong signal,
the warning lights come on
automatically.

9. Transmission vacuum modulator allows
the transmission to sift properly in the
car.
SHIFTING
ISSUES

10. Faulty vacuum modulator will cause
shifting problems or affect normal
shifting.

11. Leaked vacuum modulator diaphragm
causes a leaky vacuum and shut off the
EGR system.
POOR ENGINE
PERFORMANCE

12. If the vacuum leak is too severe, you will
notice several issues in the car such as:

13.  Less power in the engine
 Acceleration problem
 Affect fuel economy
 Deteriorate efficiency

14. Excessive emission coming out of the car
indicates a failed vacuum modulator in
the car.
PRODUCE
EXCESSIVE
EMISSION

15. Due to these reasons, an excessive
amount of nitrogen dioxide emission is
produced.

16. If you notice any of these signs in the
car, check the Transmission vacuum
modulator immediately.
CONCLUSION

17. Consult with a reputed mechanic for
repairing it as well as replace it if
necessary.
