Question about Cars & Trucks

1 Answer

I replaced the alternator on my 93 f-150 2wd 5.0 along with the battery.The reason for replacing both was the alternator started charging at 17.5 volts and burnt the battery up (battery was boiling ov

I have not had the chance to check the voltages and the resistance of any of the sensors at this time ( ie; the TSP or the idle control solenoid, EGR sensor or any other of the sensors .

SOURCE: Check engine light keeps coming on with code 332 egr code.

The Egr ports are plugged in the intake. Remove the throttle body elbow behind the throttle body, and clean out the carbon. I can walk you through it if you need me too. This is common on the 4.6

I was reading in one of my repair manuals and it says in there that there could be a block where the exhaust gas pressure sensor is. There could be a blocked inlet hose. Or it could be the ECM.

Check the EGR air passage tube again.

You may miss some on the first pass.

====


Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.


Please rate my answer if it's useful to you.

Red battery light illuminated on the dash of my 2006 Saturn ion3 4 cylinder 2.4l


The charging system on your vehicle is computer controlled . The ECM - engine computer turn's on the battery light if it think's there is a problem . Sends a message to the instrument cluster over the class 2 serial data network . Have you had the vehicle checked for DTC's diagnostic trouble code's ?

How do I replace my alternator in my 2005 GMC truck


It is more than likely an alternator problem. Charge the battery and drive to an auto parts store, and they can check the alternator on the vehicle for free.

2006 mazda tribute.The battery has been replaced and the alternator is not putting out quite the correct voltage but isn't really bad yet I don't think. It's will start ok for 4 or 5 days


Your going to need to replace the alternator, it may be charging the battery slightly and enough to get through a few days of starting the vehicle, but you will need to get the alternator replaced.

98 tiburon fx. battery blew up driving down the freeway. replaced battery, car wouldn't start. replaced crankshaft and cam sensors, along with coil pack. noticed a blown fuse for rear defogger and...


The reason why the battery blew up is because of a deffective alternator. The charging regulator on the alternator has malfuntioned, and caused the battery to be overcharged. The reason why your car wont start is because overvoltage has damaged some of the electronic sisytem in the car associated with the ignition system.

I agree with you, it sounds like the alternator isn't charging the battery. Most parts stores offer free check of your charging system, with advice on what is wrong and what needs to be replaced (you should replace your mechanic along with your alternator.)
