Should I change solenoid then clear codes and see what happens or invest the money to have it put on a diagnostic computer at a GMC dealer?

SOURCE: If I replace the delco radio in my 2003 grand am

this is not true. all the dealer needs to due is to depress the #2 & #4 preset radio buttons to get a 6 diget code so they can call GM to get the 4 diget unlock code.
They just a bunch a money, however it does require some time even for someone that knows how to do it.

I have a 1998 Nissan Maxima GLE, I Failed the Emission Inspection (DTC) Diagnostic Trouble Codes of "P1492","P1105" What these Codes exactly? mean


A code P0300 may mean that one or more of the following has happened:
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective compute
  • P1105MAP/BARO Pressure Switch Solenoid Valve
  • Check and clean the MAP sensor, or replace.
  • P1492EVAP Canister Purge Control/Solenoid Valve (Circuit)
  • Replacing the purge solenoid will clear code P1492 This should also clear code P0300 as well.

My Jimmy won't go over 2500RPM's..


Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

TRANSMISSION STUCK IN 3RD GEAR


This can be caused by several different things. First the onboard diagnostics have detected a problem and have shut the power off to the shift solenoids which defaults the transmissions to 3rd gear. Second the transmission fuse is blown ( sometimes this is called the ecm2 fuse) which kills power to the shift solenoids and defaults the transmission to 3rd gear. Third is low battery voltage or weak battery.If battery voltage drops below 10 volts sometimes the computer will put the vehicle in a failsafe mode and turn the power off to the shift solenoids ( thats right 3rd gear). These are the most common reasons but by no means the only.This should get you started , Have the codes pulled and a diagnostic run. If the transmission side of the computer is active then you know the fuse and power supply to the computer are ok. You will most likely find a code that points you in the direction of the problem.Be aware that many times the code will be for a solenoid , such as shift solenoid A . This does not mean that this solenoid is bad only that the current draw is not what the computer thinks it should be or the desired ratio is not what it should be.The computer has no way of knowing if a band is broken or a set of splines are stripped.Good Luck!

Check engine light on, Dtc shows erg insufficient flow, changed erg control solenoid and dpfe unit


Hello, since I do not know if you cleared the computer on your vehicle, the first thing I will remind you of is to clear the computer after making repairs. The Errors can continue to show for 25-35 Startups after the problem is fixed. Both Autozone and Oreillys will scan and clear your computer for free.

Next, usually on older 4.6 V-8s' but on some other models the EGR passages below the Airhorn would clog with carbon. All you need to do is remove 8 bolts and clean the groove under the Airhorn gasket and then replace the gasket. Many, many times it is not necessary to replace any other parts.

What happens is the Diagnostics are wrong because they do not measure EGR flow at the source. Flow is measured after the EGR Valve, and after all of the Solenoids. Obviously all the parts down the line can't work if there is no flow from the manifold to go through them. Quite a money maker for the Auto guys.

I hope you find my solutions very helpful in solving your problem.

Transmission wont shift out of low gear, it only does it sometimes. transmission fluid is full.what could cause it


do u have a "yellow check engine light" illuminated on the dash?? if yes, hook up the computer (code reader) and get it checked.
If it gives an unclear/confusing diagnostic then I would suggest u to start from transmission solenoid inspection/test. In most cases this is where the problem is hiding. try to replace the solenoid (buy used to save some money) and see if the problem disappears.
if changing solenoid does not help then it is pretty much clear that the transmission it self needs some work (replacement / rebuild).

Check Engine Light


There are many many problems that can cause your check engine lite to come on. Some of those problems will not let the lite go out until it is cleared with a handheld computer. (Even if the condition that caused the lite to come in, has cleared) But as far as the 2 comments go, a fuel injector cleaning would be a good invsement here. It is a good possibility that this is your problem and if it isn't, it is still very good for your engine performance and fuel consumption so wouldn't be a bad investment. If your vehicle is still under warrenty I would also talk to dealer about reading computer. Even if the check engine lite is not on, some codes will store in the computer that it came in and cleared so the dealer would be able to tell you what code came in to cause the lite to be on. It would at least be a starting point to look at for troubleshooting.
