This automotive maintenance tutorial was specifically written to assist owners of the 10th generation (2009, 2010, 2011, 2012 and 2013) Toyota Corolla in changing a failing or faulty PCV valve (positive crankcase ventilation valve) on the 2ZR-FE 1.8 liter inline four cylinder engine.

Owners of other Toyota, Lexus or Scion vehicles such as the Yaris, Matrix, Prius, Camry, RAV4, Sienna, Tacoma, Tundra, FJ Cruiser, Venza, Highlander, Avalon, Sequoia, Land Cruiser, Allion, Premio, Auris, IS 250, ES 350, GS 350, tC, xB, xD, iQ and FR-S may also find these DIY instructions to be helpful.

A few of the symptoms of a failing, faulty, clogged or stuck open PCV valve include a rough idle, misfiring, backfiring, surging, jerking, increased oil consumption, oil leaks, a CEL / SES (check engine / service engine soon) warning light, white or blue smoke from the exhaust pipe, an oily engine air filter element and reduced fuel economy (lower MPG).

There is no mention of the PCV valve in the maintenance schedule section of the Corolla owner's manual. I chose to replace the valve as part of my 100K mile service (done at 95,000 miles). If you do a lot of stop-and-go city driving, you may want to change it every 60K miles. On the other hand, if you mostly drive on the highway, you could possibly wait until 100K or 120K miles if the engine has none of the symptoms listed above.

Owners of other Toyota, Lexus or Scion vehicles such as the Yaris, Matrix, Prius, Camry, RAV4, Sienna, Tacoma, Tundra, FJ Cruiser, Venza, Highlander, Avalon, Sequoia, Land Cruiser, Allion, Premio, Auris, IS 250, ES 350, GS 350, tC, xB, xD, iQ and FR-S may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) part number for the PCV valve is Toyota 12204-37010 (also known as part # 1220437010).
