Question about 2007 Toyota Corolla

1 Answer

What is the code for a bad gas cap? I just replaced my intake manifold gasket (dealer said that was the problem and that there was a OLD code for catalytic converter) but I believe the problem is the gas cap and they wanted to charge me more, or just do not know what they are talking about. Will a bad gas cap trigger these codes too?

Codes p 0440 through to p 0459 all refer to the EVAP system.
code p 0455 refers to EVAP system very large leak which refers to a loose or missing gas cap
manifold leaks are a small leak in the codes and many are miss- read as a vacuum leak can be from the transmission actuator hose missing , and the vent controls leaking
A lot of the EVAP codes refer to the purge valve or the purge valve solenoid

SOURCE: intake manifold gasket / replace

3.8L Engine

NOTE The 3.8L (VIN K) non-supercharged engine uses a two-piece intake manifold consisting of an upper air plenum which mounts the throttle body and a lower intake manifold assembly which houses the fuel injectors. The 3.8L (VIN 1) supercharged engine uses a similar lower intake manifold. The supercharger serves as the upper manifold.
Lower Manifold

NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold. Remove the upper intake manifold to service the lower intake.
The 3.8L (VIN 1) supercharged engine uses a manifold similar to the 3.8L (VIN K), but the supercharger serves as the upper manifold.

  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Remove the upper intake manifold using the procedure above.
  4. Remove the EGR outlet pipe from the intake manifold.
  5. Detach the engine coolant temperature sensor wiring harness from the sensor.
  6. Remove the lower intake manifold bolts and carefully lift off the manifold.

To install:

  1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces and between the lower manifold and the cylinder heads..
  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Apply thread-locking compound to the bolt threads. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 11 ft. lbs. (15 Nm). Follow the toque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.

Upper Intake Manifold (Plenum)
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Tag for identification, then remove the right side spark plug wires.
  4. Disconnect the ignition wires from the fuel rail.
  5. Remove the fuel rail. Please see Section 5.
  6. Remove the cable bracket from the intake manifold.
  7. Remove the throttle body.


NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold.
  1. Remove the upper intake manifold bolts and carefully lift the upper intake manifold from the engine.

How to remove/replace the Valve Cover Gaskets on a New Beetle car?


Replace the valve cover gasket if the valve cover gaskets are leaking or if they're worn. The procedure is as follows:--
1) First of all let the motor cool down if the car was recently driven. Then remove the air intake boot.The air intake boot ios attached to the engine's throttle body.
2) Carefully disconnect the throttle cable , hoses and electrical connectors located on the upper intake manifold.
3) Then disconnect the hard pipe that is connected to the EGR (exhaust gas recirculation) valve.
4) The EGR valve is located beneath the upper intake manifold.
5) Then remove the bolts from both the upper intake manifold and the manifold support bracket.
6) Now the upper intake main fold and lower intake manifold both have got loose as you removed the nut.
7) After that remove the upper intake manifold from the lower intake manifold. Carefully place clean rags over the intake runners to prevent anything from falling into the intake system.
8) Then you will have to disconnect the crank case breather valve on the valve cover.
9) Then remove the bolts from the valve cover and remove the reinforcing straps.
10) Then remove the camshaft belt cover and the dust shield from the back of the camshaft sprocket.
11) Now carefully remove the valve cover. Properly clean the old gasket material with gasket remover.
12) You can install a new gasket in the reverse procedure of removal.


This will help. good luck.

Stalling and running rough - Hyundai Elantra - 2001-05


The Hyundai Elantra 2001 - 2005, 2.0 L engine is noted for this problem. It will lack power on acceleration and run rough and stall while driving. The engine light will come on for misfire codes. This problem is caused by a vaccum leak at the intake manifold gasket. The gasket is broken and needs to be replaced.
To replace the intake gasket with a new one, remove the 12m nuts holding the intake to the cylinder head. Then pry back( note: you do not have to completely remove the intake manifold here) the intake manifold to gain excess to remove the old gasket. Remove any excess gasket and clean with brake cleans the surface area of the intake. Install the new intake gasket on to the head and carefully install intake on to cylinder head studs. Tighten up nuts gradually and evenly to 15-20 ft.lbs.

My 2008 Chevy uplander engine light on and the code shows for cam shaft sensor and intake manifold what I do


The intake code means its leaking from the intake,bad gaskets, or a vacuum leak. check for bad gaskets on intake manifold. You can tell by putting a bit of oil around the maifold. if it is leaking the engine will flair up. To check this, External leak-- Coolant seeps through the broken intake manifold gasket to the outside of the engine. If its bad enough you will see coolant dripping from gasket. Coolant seeps through the damaged gasket to the inside of the engine, mixing with motor oil. If you suspect an internal leak, check your oil dipstick. Or if you have a substance under oil filler cap that looks like a milkshake, Oil is mixing with coolant. this means intake gaskets are bad, Now for the camshaft sensor, If you have a manifold leak. this could be giving you a false camshaft reading! Because, If sensor is bad vehicle will not start unless theres a wire problem. Symtoms of a bad sensor are--- engine sputtering, poor acceleration, stalling/inability to start. HopeI helped you out! Good-Day!

How to fix oil leaks in chevy ss impala 1996



Instructions

1. Removal

Unscrew the bolt that holds the negative connection to the Impala's battery. Set this bolt aside for later use.

Remove the engine cover to access the intake manifold and manifold gasket. Disconnect the throttle body inlet duct from the engine.

Twist off the radiator cap to allow draining of the coolant to flow more smoothly. Place an empty container beneath the radiator's drain plug, and remove this plug. Allow all of the engine coolant to drain into the empty container. Replace the drain plug once you are finished.

Tag all of the electrical wiring and hoses before removing so that reconnection is precise to factory settings. Remove these parts, individually, from the intake manifold.

Loosen the bolts that hold the intake manifold to the Impala's engine block. Lift the intake manifold from the block once all bolts have been completely removed.

Use the flat-head screwdriver to pry the old intake manifold gasket from the engine block. Discard this part once you have removed it.

Clean the engine block thoroughly with the engine degreaser and linen cloth. If necessary, use a gasket scraper to remove excess buildup and grime.

2. Installation

  • Coat the top and bottom of the new intake manifold gasket with a chemical sealer so that it bonds to the engine block securely. Position this new manifold gasket so that it lines up perfectly with the cylinder ports of the Impala's engine block.

Place the old intake manifold on top of the newly-installed manifold gasket until it aligns with all of the holes of the cylinder flanges and manifold gasket.

Attach all of the bolts with your hand to the manifold. Once all bolts have been positioned, use a torque wrench and apply 15 foot-pounds of pressure to the bolts to secure the manifold into place.

Reconnect all of the necessary hoses and electrical wiring to the intake. Pour the engine coolant back into the radiator.

Reattach the engine cover on top of the intake manifold and engine block. Start the Impala's engine and check for any leaks around the new intake manifold gasket.

P0304 Code indicates a misfire on cylinder 4
Most likely causes for this are bad wire, bad spark plug, bad coil(s) or bad dist cap if so equiped.
A vacuum leak can also cause a misfire.
Seeing the vehicle is going on 13 years old replacing the wires and the plugs would be a good place to start, and could be the solution

Took to inspection code p0171


engine running lean. Usually caused by vacuum leak. If you have a V engine, the failure is usually intake manifold gaskets. If you have inline (4-cylinder), the cause may be intake gaskets or bad or unhooked vacuum hoses attached to the intake manifold. Check all vacuum hoses for cracks or loose connections. Replace any suspect hose. To find manifold gasket leaks, spray ether or carb cleaner on the gaskets with the engine running. If the engine revs at all, you have a leaky gasket and must remove the manifold to replace. Please let me know if you have any more questions.

Windstar 2000 3.8. Runs fine. Checked for codes and got p0171 and p0174. Cleaned the MAF sensor. Went to erase codes and found the there is a third one in there now. p0113. What is wrong?


The upper intake manifold gaskets and isolators (the bolts that hold the manifold down) leak and cause the p0171 and p0174. The reason they leak is due to a missing baffle in the front valve cover which allows some oil into the upper intake which swells the gaskets and wears them. The manifold gaskets and valve cover should be replaced. But before having this done check to see if the black plastic hose on the back of the rubber intake hose(between the throttle body and maf) has dislodged. This happens alot when a new air filter is installed and will cause the same codes.
