Repair P0301 Misfire P0171 Lean Toyota Camry √ Fix it Angel

My mechanic told me I had misfire in 2 cylinder. He replaced the plugs, but says I also need an ignition coil. What is the numbering sequence in the coils? I'm going to replace it myself and don't know which one is 2.

Best Answers. February edited February Accepted Answer. Ken Do not pay a mechanic to replace these coils, it is two nuts and one bolt to do it yourself. Remove the plastic cover over your engine block where you put oil in the engine, it is two 10 mm nutsunderneath you will find your coils, either four or six depending on whether or not your engine is 4 or 6 cylinder. The bolt in the coil is 10 mm also, as you look at the coils they are numbered from left to right, 1 coil is all the way left if you are facing the engine.

Unplug the wire harness from the back of the coil, pull up on it and it pops right out your spark plugs are underneath it FYI if you want to change those yourself also, one plug under each coil.

Sorry to all of those that were fleeced by mechanics. I'm sure you could find a diagram on your models engine which will help you locate coils. Those are just thumb caps and they can be removed with a little pressure and simply unscrew them.

A pair of needle nose pliers can be used to push them if they are too tight to remove by hand. The 2 coil is the second one in order from the timing belt. So standing in front of the car, the timing belt is on your left the cylinder ID's are 1,2,3,4. February Thanks brian I'm changing the coils, thanks to info from youtube video but I ran into a problem. In addition to the two 10mm nuts on the manifold cover, there are two plastic round plastic restraining clips at the rear of the cover.

I see nothing on video that describes them, so I don't know how to release them.A part of understanding the basics of a V8 engine is to know how the cylinders are numbered. According to BoxWrench, "Cylinder numbering refers to how the bores within the block are oriented and numbered. A V8 engine has eight cylinders, with one cylinder placed beneath each spark plug below the two valve covers on each half of the engine. Four cylinders sit on both the right and left sides of the engine, for a total of eight.

To determine the location of parts on a car or truck or its engine with regard to left or right side, the accepted method is from sitting inside the car. When looking at the V8 engine for cylinder placement, keep in mind that and references to the right and left side of an engine will be reversed, when compared with sitting inside the car.

There is not one standard method for having the cylinders numbered on a V8 engine. Each manufacturer chooses its own system, or uses a basic method shared by other manufacturers, since this is not necessarily considered a proprietary element in the operation of an engine or its design. In the most common method for cylinder numbering of a V8 engine, when facing the engine from the front of the car, the cylinder on your actual right side and closest to you is the number one cylinder.

Then jumping to your actual left side, the closest cylinder to you is the number two cylinder. This back and forth counting continues in this pattern for all eight cylinders. In effect, all odd-numbered cylinders are on your actual right side, while all the even numbers are on your left side. Basically if the V-sides of the engine were folded into each other, the cylinder numbers would fall inline and in order. Ford Motor Company numbers its cylinders along each side from front to back.

When looking at the engine, start on your actual left-hand side with the cylinder closest to you as number one, followed by two, three and four. Then look to your actual right-hand side; the cylinder closest to you is number five, moving along the line away from you to number eight. The cylinders in any engine, V8 or otherwise do not all fire at the same time.

Each cylinder takes its turn in a predetermined rotation, which is not the same order as the cylinder numbering. According to BoxWrench, the basic Ford firing order is as follows: First cylinder number one, followed by five, four, two, six, three, seven and finally number eight; then the rotation begins again and continues while the engine is in operation.

The firing order may change between models, even when the manufacturer uses a standard firing order for other modes. Its always best to check the owner's manual for specific firing order.

Site Navigation. I have a 4wd limited v6.

toyota v6 cylinder numbering

I have changed the spark plugs i have changed coil pack on the number 6 cylinder, and I'm still getting a a misfire. I also have a viberation when you crank it up and about 50 mph. What could be wrong? Thanks for any help. I'm going through the same thing now I made a separate post basically layng out what my mechanic is doing to try to sort it out.

I'm having the same problem P on my V6 2WD with k miles. I replaced spark plugs and swapped coils and still getting the misfire code. The code occurs when I first start up the engine and it shakes for about 30seconds to 1 minute. Then it runs perfectly fine. I filled the coolant reservoir to the full line and after about a week the reservoir is at about half.

So like Toyota tech said coolant is leaking into the cylinder head. I'm kinda a noob on this just learning all these things from other posts here on T4R. I'm wondering if replacing the head gasket will solve this issue. Toyota tech you said you ran into this issue at your dealer.

I need the firing order

Do you know how much this repair would cost? I'm in the Los Angeles area and I'm wondering if I should take it to a local shop or to the dealer. I usually do all my vehicle maintenance myself but after reading the repair manual it seems like this issue is out of my leauge, plus I don't have a garage to store the truck in to do the repair.

Brad, Dodger did you get your vehicles repaired? How much was it? Last edited by Flo4Run; at PM. Originally Posted by bradUnfortunately, it also ended the run of the excellent 3.

That was pretty much an accident. Still, for those lucky owners that opted for the V6, it was a pleasant one. It was middle of the road.

However, time marches on. Fuel economy is often one of the top criteria shoppers now consider when selecting a vehicle. The percentage of takers was low and getting lower. Standardizing on a 4-cylinder engine bay keeps things simple. For those that want a smidge more power and also better fuel economy, the new RAV4 Hybrid might do.

For those that want a Toyota-family of brands vehicle with more power the Lexus NXt and its 2. One could argue that the RAV4 with a V6 might be better in some ways than either of these new choices, but the NXt is also selling strongly. In fact, since it entered production it has outsold the BMW X3 every month.

Like many RAV4 owners I also own a 6-cylinder, compact Toyota crossover from that generation, mine being a Highlander.

It is easy to understand why the owners of the older RAV4 V6 miss it, but based on what Toyota and Lexus are saying and doing, there is no evidence it is ever coming back. More on Page 2.

The new engine very soon became a popular choice for mass-produced Toyota's vehicle such as Toyota Camry, Toyota Rav4, and Highlander.

The V-angle between cylinder banks is 60 degrees. The liners are cast into the block material. The engine has a forged steel crankshaft with five counterweights and forged connecting rods.

The aluminum alloy pistons have resin-coated skirts to reduce friction. The engine block is equipped with oil jets which spray oil on the pistons and reduce their temperature. Each cylinder head is a three-piece unit: the cylinder head itself, the camshaft housing, and the valve cover. All components are made of aluminum alloy. There are steel-laminate type head gaskets between cylinder banks and heads. The engine has double overhead chain-driven camshafts the intake and exhaust camshafts for both cylinder banks.

The primary timing chain drives the intake camshafts only; the exhaust camshafts are driven by intake camshafts via secondary chains. The valves are actuated via roller rocker arms. The valve clearance is automatically adjusted via hydraulic lash adjusters tappets. The 2GR engine has a variable geometry intake manifold made of plastic.

The Toyota's ACIS varies the length of the intake manifold according to engine rpm by open and closes the intake air control valve. The acceleration pedal doesn't have a physical connection with the throttle body, just position sensor, and wires. Each spark plug has an individual ignition coil integrated into the spark plug cap.

The exhausts gases go out through the stainless-steel exhaust manifolds headers and a three-way catalytic converter on both sides. That version features Toyota's D-4S twin injection system direct and port fuel injection. The combination of the direct injection and conventional port injection requires separate low- and high-pressure fuel systems. The engine also got new cylinder heads with high-pressure direct fuel injectors positioned at the outer side of the intake valves.

The pistons have redesigned shape and are made of a hypereutectic aluminum alloy to withstand high loads. Due to the ability to provide better cooling of air-fuel mixture by direct fuel injection into the combustion chamber, the compression ratio was increased up to But a few years later, this engine became a standard V6 engine for the Toyota Camry and Highlander.

The engine kept the architecture and received the last Toyota's advanced technologies in the engine development. The engine still uses a variable exhaust valve timing VVT-i. The significant changes are observed in the exhaust system. Now, the exhaust manifolds are integrated into the cylinder heads and the EGR circuit is cooled. The reason for that became a problem with an oil leak from the rubber hose which feeds the VVT-i lubrication system. The manufacturer replaced that rubber part by a metal pipe.

If the 2GR engine has a damaged cylinder wall surface, the entire cylinder block has to be replaced. The thin walls of the cylinder liners make the engine impossible to bore the block. The liners itself are cast into the aluminum engine block.
