Toyota Rodent Wire Damage: Common Chew Points & Repair
Toyota is the most common make on the Peninsula, so it is also the make we repair most often for rodent damage — just down the street from the San Bruno Toyota dealer. Rodents usually go for the engine harness, the injector and knock sensor wiring, and the cabin air filter housing behind the glovebox.

Frequently Asked Questions
Does my Toyota warranty cover rodent damage?
Generally no. Toyota's new-vehicle warranty covers defects in materials and workmanship, and rodent damage is treated as outside damage. It is often covered by the comprehensive portion of your auto insurance instead.
Can an independent shop repair rodent damage on my Toyota without affecting the warranty?
Yes. Repairing damage at an independent shop does not void the rest of your Toyota warranty (Magnuson-Moss Warranty Act). We use OEM Toyota pigtails and harness sections.
Why do rats chew the wires under my Toyota's intake manifold?
The valley under the intake on V6 engines is warm and enclosed — an ideal nest. That is why knock sensor circuit codes are a classic sign of rodent damage on V6 Camry, Highlander, Sienna and Tacoma models.
