SOURCE: 2004 Lexus RX330 Battery Replacement

You just had to disconnect the negative off the old battery first. Then you disconnect the positive and it happens to touch metal it won't short anything out. Make sure you can not wiggle the cables, that the connectors at the battery can't spin or move at all. Tighten them more if necessary, try to start it. Let me know if you still have problems.

SOURCE: 2004 lexus rx330 what does vsc light indicate

VSC is Vehicle Stability Control. This is and electronic sensing which monitors and combines performance of braking, wheel slippage and handling, ect.
If this light comes on along with check engine light, it can be caused by a loose gas cap or faulty o2 sensor.

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.

Thank you for using FixYa, have a nice day.

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!

P0012 Intake camshaft position timing over retarded bank one Is this a easy fix


Code P0012 - Variable Camshaft Timing Over Retarded - Bank 1

How does a P0012 code trigger the check engine light? This code will trigger the check engine light under the following condition:
* The comprehensive component monitor, referred to as the CCM, monitors the Variable Camshaft Timing (VCT) position for over-retarded cam timing. If the cam timing exceeds a maximum calibrated limit or is stuck in a retarded position, the check engine light will come on and set this trouble code.

Possible Causes:
Incorrect camshaft timing
VCT solenoid valve stuck open or continuous oil flow to piston chamber
Camshaft advance mechanism binding, or faulty VCT unit

Diagnostic Help:
This check engine light code is caused by a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Possible symptoms may include rough idle, stall or hard start. Refer to manufacturer specific component tests for the VCT unit. You may also use the "Get Help" link if you need specifications or have any other related questions. Remember to refer to an appropriate manual for specific instructions.

Other details mentioned 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)

Possible Solutions:
The main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. 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.

Hope helps (remember to rate and comment this).
