Warning Light???

[pan]

Buddy has a 2001 Firebird. Yesterday tried to leave and the car started fine ran normal, but warning light came on and the car wouldn't rev. you give it gas and nothing happened let the clutch out and it would idle down the road but nothing. Any help would be appreciated never had the problem myself or a V6 for that matter lol. thx in advance!!!

Your buddy needs to take it to autozone and have the codes read. That will tell him where the problem is at.

Well, okay then. Since you want to be such a smartass, why don't you tell us exactly what light it was then? There are about a dozen "warning" lights on the dash of these cars, how about you pick one?!?! Don't come in here and think that we are stupid because we can't read your damn mind. Fill us in and quit looking like a dick!

Tony chill man hes only got 30 some odd posts....... what he meant was, try not to put so broad of a discription and we can help you out easier.

Not being a smartass or a dumbass for that matter i know a little about cars since the family owned a race shop for about 20 years lol. But what i was saying is i'm not a V6 man at all or computers. But i meant the light on the dash said "WARNING" not check engine. As for explaining the problem i said all i can say about the problem. The car while the warning light was on the throttle would not work but the car would run and idle fine and even idle down the road but no throttle. I mean to me imo that's about as close to the problem as you can explain. As for the 30 posts lol. theres not much i can't figure out on a car or do myself so don't need alot of posts and stay busy with work and school fulltime to stay on here and help people as much as i wouold like to. But hey to all that reply

i was trying to help you out Pan with the comment of 30 posts saying your new to the forums. any way, im not familiar with a light that simply says " warning" very odd, ive never seen it on a v8 fourth, maybe its just a v-6 light? i dont recall it being on my girlfriends camaro.... is it a red light or amber?

OK. talked to my buddy again which isn't much on wrenching! He said the light said " REDUCE ENGINE POWER" not warning. So maybe that will help?

I would like to bring to everyones attention that the above is the politically correct answer. While I respect it, I prefer the not so politically correct answer tony made hahaha.

Ok heres your answer to your "warning light" lol:

DTC P1518 Throttle Actuator Control (TAC) Module Serial Data Circuit

Have your codes scanned it should be throwing a P1518 code.

Heres how it works:

DTC P1518 Throttle Actuator Control (TAC) Module Serial Data Circuit

Circuit Description
The TAC module and the PCM communicate via a dedicated serial data circuit. This serial data circuit is separate from any other serial data circuit on the vehicle. Accurate transmitting and receiving of serial data requires not only good circuit integrity but also adequate system voltage. This diagnostic monitors the accuracy of the serial data transmitted between the TAC module and the PCM. If the PCM/TAC module detects a loss of data or invalid data, this DTC sets.

Conditions for Running the DTC
The ignition switch is in the crank or run position.

Conditions for Setting the DTC
Invalid or missing serial data messages are detected for a predetermined amount of time.

Action Taken When the DTC Sets
The PCM will illuminate the malfunction indicator lamp (MIL) during the first trip in which the diagnostic runs and fails.
If equipped with traction control, the PCM will command the EBTCM via the serial data circuit to turn OFF traction control and illuminate the TRACTION OFF lamp.
The PCM will store conditions which were present when the DTC set as Freeze Frame/Failure Records data.
Conditions for Clearing the MIL/DTC
The PCM will turn OFF the malfunction indicator lamp (MIL) during the third consecutive trip in which the diagnostic has run and passed.
The history DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
The DTC can be cleared by using a scan tool.
Diagnostic Aids
Inspect for the following:


Important
DTC P1518 sets if the battery voltage is low or the PCM is replaced/reflashed. If the customers concern is slow cranking or no crank because battery voltage is low, ignore DTC P1518. Clear any DTCs from memory that may have set from the low battery voltage condition.


The following could cause an intermittent condition:

Many situations may lead to an intermittent condition. Perform each inspection or test as directed.

Important: : Remove any debris from the connector surfaces before servicing a component. Inspect the connector gaskets when diagnosing or replacing a component. Ensure that the gaskets are installed correctly. The gaskets prevent contaminate intrusion.


• Loose terminal connection

- Use a corresponding mating terminal to test for proper tension. Refer to Testing for Intermittent Conditions and Poor Connections , and to Connector Repairs in Wiring Systems for diagnosis and repair.

- Inspect the harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and faulty terminal to wire connection. Refer to Testing for Intermittent Conditions and Poor Connections , and to Connector Repairs in Wiring Systems for diagnosis and repair.

• Damaged harness--Inspect the wiring harness for damage. If the harness inspection does not reveal a problem, observe the display on the scan tool while moving connectors and wiring harnesses related to the sensor. A change in the scan tool display may indicate the location of the fault. Refer to Wiring Repairs in Wiring Systems for diagnosis and repair.

• Inspect the powertrain control module (PCM) and the engine grounds for clean and secure connections. Refer to Wiring Repairs in Wiring Systems for diagnosis and repair.

thx man i'll tel him what to do if it does it again!

[erniez28]

No porblum. Hope that helps out. I guess they didn't equip the v8s with that option? I dunno lol.
