The P2101 fault code in the UAE most commonly indicates a failure of the Throttle Position Sensor (TPS), issues with its wiring harness (like short circuits or corrosion), or a malfunction within the electronic throttle body motor itself. It is not typically solved by immediately replacing the entire throttle body assembly. According to common inspection reports from RTA Dubai's vehicle testing centers and technical guidelines referenced by MOI UAE for vehicle safety, sensor and electrical connection failures are a primary cause of electronic throttle control (ETC) system warnings. For a common GCC-spec vehicle like a 2018 Toyota Camry, the repair cost can vary significantly. If it's just a dirty throttle body, a professional cleaning at a garage in Sharjah Industrial Area might cost around 150-250 AED. However, a genuine Throttle Position Sensor replacement, including part and labor at an authorized dealer in Dubai, can range from 800 to 1,500 AED. If the issue is a damaged wiring harness due to heat or wear—a common problem given summer temperatures above 45°C—repairs could add another 300-600 AED. The total cost is rarely below 500 AED for a proper fix. Attempting to clean it yourself might offer a temporary fix for rough idling on a dusty road, but the code will likely return if the sensor itself is faulty. Always get a proper diagnostic scan to pinpoint the exact cause before any repair.
