Toyota Camry V6 2GR-FE Spark Plugs & O2 Sensor Replacement

This video will show you step-by-step how to replace the spark plugs and optionally, the rear oxygen (02) sensor on a 2006 V6 Toyota Camry V6 with the 2GR-FE engine. The replacement service interval for these spark plugs is approximately 100,000 miles and use iridium spark plug technology. The GR-FE series engines replaced the timing belt driven MZ-FE engines. They were first available on the 05 Avalon and towards the last year of 06 Camry's. The GR-FE engines were subsequently used on later model Lexus vehicles using the V6 (i.e. ES350 and RX350) along with the Sienna, Venza, RAV4 and Highlander. Most of these vehicles have their windshield wiper motor cowling extending into the engine compartment over the right bank of the transversely mounted engine and transmission. In addition, the intake plenum rests over the right engine bank making it almost impossible to get to the right bank spark plugs unless the cowling and plenum are first removed. The GR-FE also uses a plastic intake plenum replacing the heavier all aluminum alloy plenum.
Oxygen sensors almost wear out (poor and/or weak electrical signal to the PCM(Power Train Control Module)) at the same rate as spark plugs so it may be a good idea to replace the sensor(s) with the plugs. When the O2 sensor goes bad, you have no choice but to replace the sensor. Your car's PCM will ignore the erratic O2 sensor signals but will allow you to operate your car with an over rich air/fuel mixture. The rich air/fuel mixture prevents the car from a potential over lean air/fuel mixture which can overheat and damage the engine. The over rich mixture will results in a drop in fuel efficiency and within a few months burn out your catalytic converters. The burn out is caused by excess hydrocarbons (unburned fuel) being burned by your cats. The excess heat eventually destroys the converters. When your check-engine or MIL goes on because of the O2 sensor, and the longer you ignore it, the sooner you'll burn out your cats. So if you think O2 sensors are expensive, check out the cost of a new cat on these cars. You can buy new discounted OEM Denso sensors for a little over $100.
