Which Sensors Commonly Fail o r Malfunction in EFI-Converted Suzuki Khybers?

For those who’ve converted their Khybers to EFI, which sensors are most likely to give problems in the long run? I’m thinking of keeping spares for the most failure-prone ones. Do sensors like the O2, TPS, o r MAP usually go bad more often in Pakistani conditions?

Based on feedback from Pakistani car electricians and owners, the following sensors are the most failure-prone in EFI-converted Khybers:

Frequently Failing Sensors:
Oxygen O2 Sensor: Often fails due to local fuel quality o r improper exhaust installation.

TPS Throttle Position Sensor: Fails due to misalignment o r water/dust exposure.

IAC Valve: Gets dirty o r stuck due to intake grime and lack of cleaning.

MAP Sensor: Sometimes wrongly installed o r incompatible, especially when retrofitted from other vehicles.

Coolant Temperature Sensor: Gives false readings, especially when cheap aftermarket parts are used.

Advice:
Always go for Denso, Delphi, o r Bosch brand sensors when possible.

Avoid cheap local o r Chinese replicas.

Clean sensors regularly and ensure they are mounted away from heat and moisture.
