3. Step-by-Step DIY Repair Guide for Toyota Camry TRD
Read ECT live PID on scanner. If it reads 284°F (140°C) or higher with engine cold, a short to ground exists. on the Toyota Camry TRD equipped with 3.5L V6 DOHC 24V with Dual VVT-i (301 HP / TRD Cat-Back Exhaust).
Unplug sensor connector while watching live data. If temperature drops to -40°F (-40°C), the sensor itself is shorted. on the Toyota Camry TRD equipped with 3.5L V6 DOHC 24V with Dual VVT-i (301 HP / TRD Cat-Back Exhaust).
If reading stays pegged at max with sensor unplugged, inspect harness for pinch points grounding against engine block. on the Toyota Camry TRD equipped with 3.5L V6 DOHC 24V with Dual VVT-i (301 HP / TRD Cat-Back Exhaust).
Allow engine to cool, unscrew old ECT sensor from coolant crossover pipe or thermostat housing, install new OEM sensor with fresh thread sealant. on the Toyota Camry TRD equipped with 3.5L V6 DOHC 24V with Dual VVT-i (301 HP / TRD Cat-Back Exhaust).
Bleed air from cooling system, clear DTCs, and verify normal temperature rise on live data. on the Toyota Camry TRD equipped with 3.5L V6 DOHC 24V with Dual VVT-i (301 HP / TRD Cat-Back Exhaust).
