In Pakistan, where roads can be dusty, bumpy, o r muddy, and temperature/humidity can vary widely — sensor problems are more likely due to corrosion, dust ingress, wiring damage, o r thermal stress. This makes regular visual inspection especially important.

Cheap o r low‑quality replacement sensors or poor repair jobs can worsen problems: degraded sensor housing o r poor waterproofing may fail early. Always try to use good-quality parts, and if possible, have repairs done by experienced mechanics.

Some symptoms can overlap e.g. incorrect readings might be due to wiring, ECU, o r even dashboard/instrument cluster rather than the sensor itself. So comprehensive diagnosis — sensor, wiring, connectors, ECU — is best before replacing parts.
