The 2009 Matrix with the 2.4L engine should be avoided, as some engine problems could be expensive to repair. More about the problems: A failed rear oxygen sensor (Bank1 Sensor2) could cause the code P0138. it's caused by a faulty camshaft timing gear assembly (VVT gear). The VVT gear must be replaced to correct the problem. The repair 1. Dual VVT-i. The dual VVT-I system adjusts timing on the intake and exhaust camshafts. This technology was first introduced in 1998 on the RS200 Altezza's 3S-GE engine. It is also found on Toyota's new generation V6 engine, the 3.5L 2GR-FE that debuted on the 2005 Toyota Avalon. Why Toyota VVT-i engine may start to consume oil and how to do oil leak test. Oil consumption is bad signal. By Jon LeSage - August 7, 2015. This article applies to the 5th generation Toyota Camry (2002-2006). If you're driving a 2002 to 2006 Toyota Camry, there are common engine problems that can come up that must be fixed right away to avoid severe engine damage. They might start with common signs, such as using up engine oil faster than normal. The VVT-i system works by using an oil-pressure actuator to adjust the location of a camshaft. This results in better low-end and high-end performance and overall engine efficiency. Early 1GR-FE engines only used VVT-i on the intake camshafts. That changed in 2009, when Toyota added Dual-VVT-i to the 1GR-FE in the 4Runner and FJ Cruiser. Pentastar 3.6L Common Problems. Some of the most common issues with the Dodge, Jeep, Ram, Chrysler 3.6 Pentastar engine include: Cylinder head (2011-2013) Rocker arms. Cooling system. Oil pump. Below we break down each of these problems in-depth. It's a good time to add a few quick notes. 2.4L: 2.4 liter; I4 : 4 cylinder engine; 16V: 16 valves ,or, 4 valves per cylinder. VVT: variable valve timing. 172 hp: 172 horsepower. For the best answers, search on this site The 2.0l refers to the displacment in metric terms of 2 liters. The L4 refers to the engine design and cylinder numbers. I agree with you on every count. The 1.33 is a big disappointment - the awful gearbox (and this really is a terrible gearbox), the engine that holds onto revs, the listless power. The stop start can be turned off, so that is not too much of an issue. A range of five engines is available in the Auris. The two petrol powerplants comprise a 96bhp 1.4 VVT-i unit and a 122bhp 1.6-litre Dual VVT-i. Both use variable valve timing technology to improve fuel efficiency and power output. Diesel buyers get to choose from three engines. The entry-level lump is the 1.4-litre D-4D, good for 89bhp. The 2TR-FE has a cast iron, deep-skirt cylinder block. A 95.0 mm (3.74 in) cylinder bore and 95.0 mm (3.74 in) piston stroke give the 2TR-FE engine a total of 2693 cc of displacement. Compression ratio rating is 9.6:1 or 10.2:1. The 2TR-FE is equipped with twin counter-rotating balance shafts within the crankcase to cancel the secondary inertia VVAPBDI.
