Rattling noise from right side of engine

Noise seems to be coming from the DTC area. i removed the front solenoid control valve and then reinstalled. i have also changed the oil and corrected all oil leaks. took vehicle to the dealer and they stated that they would have to remove the engine and check wear on the gears. i talked to a friend and they stated that they rarely seen that problem and said its usually the solenoid control valves. any help...

    the noise does not happen at idle and usually begins when accelerating around 2k. its coming from the right front area of the engine, almost sounds like a bad belt tensioner. i believe its the solenoid control valve keep opening and closing. i am replacing the lower oil pan gasket and performing an oil change just to eliminate any possibilities. if that does not work i will either replace both cam sensors and crank sensor as there is a bulletin about those or both solenoid control valves. i will keep in touch, thanks for the quick response. eric

    Did you ever figure this problem out? I have a rattling noise that seems to
    only appear on certain engine vibrations. on a fast take off it doesn't happen.
    Or high RPM's only a certain RPM makes the rattle sound off. I can't find
    it anywhere.

    I also have the same problem with my 2006 Nissan Murano. Rattling noise that seems to come from right side of engine and usually goes away after about 10 miles of driving.

How can I replace transmission control solenoid?


Control solenoid ? explain . Shift solenoid , pressure control solenoid ?
The shift solenoid valves are two identical, normally open, electronic exhaust valves that control upshifts and downshifts in all forward gear ranges. These shift solenoid valves work together in a combination of ON and OFF sequences in order to control the positions of the 1-2, 2-3 and 3-4 shift valve trains. The PCM monitors numerous inputs in order to determine the appropriate solenoid state combination and the transmission gear for the vehicle operating conditions
The pressure control (PC) solenoid valve is a precision electronic pressure regulator that controls transmission line pressure based on current flow through its coil windings. As current flow is increased, the magnetic field which is produced by the coil moves the solenoid's plunger further away from the exhaust port. Opening the exhaust port decreases the output fluid pressure, which is regulated by the PC solenoid valve. This ultimately decreases line pressure. The PCM controls the PC solenoid valve based upon various inputs including throttle position, fluid temperature, MAP sensor, and gear state.
Did you have a DTC - diagnostic trouble code ?

Where is vct solenoid


Hi there:A code P0012 refers to the VVT (Variable Valve Timing) or VCT (Variable Camshaft Timing) components and the car's PCM (Powertrain Control Module, also called an ECM).
That consists of a few different components but the P0012 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-********, the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft.


A P0012 DTC trouble code may be caused by one or more of the following:

- Incorrect camshaft timing

- Wiring problems (harness/wiring) in intake timing control valve control solenoid system

- Continuous oil flow to VCT piston chamber

- Failed timing valve control solenoid (stuck open)



On Ford, the VCT solenoid is located at top of cylinder head underneath the valve cover and goes around one camshaft. You will need to remove the valve cover, the timing cover, then remove the timing belt, the camshaft sprockets, and finally the camshafts to remove the vct solenoid as it goes around the camshaft. You can use 2001-2003 models with same engine.



VCT or Variable Cam Timing solenoid is a device used in modern engines to change camshaft position timing in relevance to engine speed and engine timing allowing the engine to produce more horsepower without adding excessive overlap to the camshaft design.


The way the VCT Solenoid works is as follows:
The VCT solenoid works with oil pressure, it receives a signal from the ECM when the camshaft needs to be rotated either in the advanced mode or ******** mode depending on engine load and speed.The VCT solenoid is able to accomplish that by altering the oil flow in the passages that lead to the cam phaser(s), there are passages to advance the valve timing ( open the valves earlier), and passages that direct the oil to ****** the valve timing ( open them later)

The purpose of the VCT or Variable Cam Timing system is to allow the engine to move larger volumes of air in and out of the cylinders to generate maximum horsepower.
Vehicles with DOHC ( Dual Overhead Cam ) engines usually have two VCT solenoids mounted in each cylinder head, one for each camshaft, allowing the Engine Control Computer to activate each VCT timing mechanism in each Camshaft separately.
NOTE: The Cam phaser is mounted on the front of the camshaft(s) it is driven by the engine's timing chain or timing belt depending on the engine's design.



Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Fault code P0021


Hi there:P0021 - "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2)

A code P0021 refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0021 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft. A P0021 engine code is basically the same as a P0011 code, except this is for Bank 2, not Bank 1.

Most likely a P0021 DTC will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.


A P0021 DTC trouble code may be caused by one or more of the following:Incorrect camshaft timingWiring problems (harness/wiring) in intake timing control valve control solenoid systemContinuous oil flow to VCT piston chamberFailed timing valve control solenoid (stuck open)

Possible Solutions:This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.To reset the fuel pump, press the button on the switch. The switch is located immediately below the hole in the trunk side trim.

How do I change a vct solenoid on a 2007 f150 5.4


The VCT solenoid is located under the valve cover toward the front. There are a total of two solenoids, one on each bank (side). If you look at the valve cover you will see a harness and connector going to the solenoid with the top of the solenoid sticking through the valve cover. Remove the valve cover for the affected side, place a shop rag at the timing chain area to keep debris or bolts from falling in. Unfasten the solenoid and simply pull it straight out. Replace the solenoid, remove the rag and reinstall the cover. Be sure to remove the rag :o)

That being said, the main cause of VCT codes or a noise from the VCT is caused by the camshaft phaser. This is the mechanical part of the VCT system and mounts to the front of the camshaft. It operates by oil pressure that is controlled by computer signals to the solenoid.

If the solenoid is sticking, I've had luck taking a 12 volt power source and applying power and ground to the two pins at the solenoid, touching the terminals a few times. This sometimes frees the solenoid and brings the vehicle back to normal cam timing. A fresh oil change with a factory motorcraft filter will help keep the system clean and free from VCT concerns.

Some aftermarket oil filters will start to come apart, sending paper into the oil channels. This affects the oil pressure, the very pressure that the VCT system needs to work. I hope this info helps. If for any reason you can't give four thumbs up, please request more information. Good luck!

P0977


Shift Solenoid B Control Circuit High

Areas to check:
  • Short in shift solenoid valve No. 2 circuit
  • Shift solenoid valve No. 2
  • ECM

  • Check the shift solenoid valve No. 2 when DTC P0976 and P0977 is output.
  • Check harness and connector between ECM and shift solenoid valve No. 1 or No. 2.
To check the Shift Solenoid Valve No. 2:
  1. Jack up the vehicle.
  2. Remove the oil pan.
  3. Remove the shift solenoid valve No. 1 or No. 2.
CHECK:
  1. Measure the resistance between the solenoid connector terminal and the body ground. Standard: 11 - 15 W at 20°C (68°F)
  2. Connect the battery positive lead to the solenoid connector terminal and the battery negative lead to the solenoid body ground. Standard: Solenoid operation noise is produced. If not, Replace solenoid valve. If the Solenoid operation noise is produced, Check and replace the ECM.

I have a 2001 caddy deville that i am buying there is a code that comes up P1860 can you tell me what that is Thank you Paul


Circuit Description with 4T80-E Automatic Transaxle
Ignition voltage is provided to the torque converter clutch pulse width modulated (TCC PWM) solenoid valve. The PCM controls the ON and OFF time of the solenoid by providing a ground through the output driver module (ODM) . The PCM uses a PWM duty cycle, in order to control application and release of the TCC. When the solenoid is commanded OFF, the PCM senses high volts. When the solenoid is commanded ON, the PCM senses low volts. If the PCM detects a continuous open, short to ground or short to voltage in the TCC PWM solenoid valve circuit, then DTC P1860 sets. DTC P1860 is a type B DTC.

Conditions for Running the DTC
  • The system voltage is 8-18 volts
  • The engine run time is greater than 5 seconds.
  • The TCC PWM solenoid valve duty cycle is 10% or less or 90% or greater.
Conditions for Setting the DTC
The TCC PWM solenoid valve feedback circuit indicates a continuous open, short to ground or short to voltage for 4.3 seconds.
