This automotive maintenance tutorial was specifically written to assist owners of the third generation (2014, 2015, 2016, 2017, 2018 and probably also the 2019 and 2020 model years) Toyota Highlander SUV in changing a faulty camshaft position sensor in a 2GR-FE or 2GR-FKS 3.5L V6 engine that is part of the Dual VVT-i (variable valve timing with intelligence) system.

Owners of other Toyota, Lexus and Scion vehicles such as the 4Runner, Avalon, 86, C-HR, Camry, Corolla, iM, Land Cruiser, Mirai, Prius, RAV4, Sequoia, Sienna, Tacoma, Tundra, Yaris, FR-S, xB,  xD, tC, xA, CT 200h, ES 250, ES 300, ES 330, ES 350, IS 250, IS 350, RX 300, GS 250, NX 300 and RX 350.

The OEM camshaft position sensor was marked as Denso part number 11T18-1290 (also known as # 11T181290 or 11T18 1290).

A few other compatible replacement camshaft position sensors with their part numbers are as follows: Beck Arnley 1800499, Airtex 5S6281, Delphi SS10939, Standard Motor Products PC559 and Denso 1961001.


If you have a CEL / SES (check engine light / service engine soon) light illuminated on the gauge cluster, your OBD II (OBD 2) scan tool might display one of these VVT or camshaft position sensor related DTC (diagnostic trouble codes): P1349, P1354, P0021 or P0011.

The first two steps are to open the hood and then pull off the foam rubber engine cover.

Set the engine cover aside in a safe place.

There are two camshaft position sensors on the front of the engine and two more on the rear of the engine closer to the firewall.

In the picture above, I'm pointing to the two camshaft position sensors on the front of the engine. The one on the top left of the picture is the intake side bank 2 sensor. The other one on the bottom right side of the picture is the exhaust side bank 2 sensor.

Replace Rubber Cover
Tighten the bolt in the clockwise direction with the 10mm socket and a 1/4" drive ratchet until it is snug.

Try to avoid over tightening the bolt to prevent from cracking the plastic sensor housing.

Push the rubber cover back into place over the top of the engine.

The friction fasteners on the underside of the cover should be pushed down on to the metal pegs on the top of the engine.

Be sure to record the camshaft position sensor replacement in your vehicle's service records.
