Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Multiple, seemingly unrelated engine-related faults appearing together
  • Check Engine light constantly on with numerous fault codes
  • Engine running poorly or not starting

Installation information

Routes throughout the engine bay to each sensor and actuator — requires careful attention to correct routing away from heat and moving components.

Frequently asked questions

This harness connects to numerous engine components simultaneously — physical damage to a section carrying multiple circuits can disrupt several systems at once, even though each component itself may be perfectly healthy.

  • I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

  • No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

  • Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
