Question about 2008 Chevrolet Malibu

1 Answer

I have a 2008 malibu Lt. i getting the trouble codes p1516,2101 and 2176 on the dis play it says idle speed control the tac motor ckt range. tac syetem idle position not learned. and it does this when i try to crank the engine it has a delay sometimes and whe this happen the codes pop up. the engine starter will not crank over but if i just hold the key on start the srarter do not spend over right away it delays. it also say the traction control code is pending. when i clear the code it runs ok for a day. i clean the throttle body and check the spring to make sure it was hoiding spring tension. not sure if i have to replace the ECM

The torque converter clutch circuit may be at fault. The best way to determine the problem is to have a scanner/computer to read check engine codes.

Check your fuel pump presure. Pump is in the tank. Also try and loosen the fuel cap, the tank vent may be stopped up.

COULD THE GAS PEDAL CABLE CAUSE THIS CODED PO507 to be high


Extracted from Engine-Codes.com

Code P0507

Possible causes

- Dirty throttle body

- Electric throttle control actuator misadjusted or damaged

- Faulty Electric throttle control actuator

- Intake air leak

- Poor electrical connection to the Intake Air Control (IAC) valve


help.jpg What does this mean?

Tech notes

If there are no intake leaks, clean throttle body, adjust engine idle and erase engine code. If the code comes back you may have to replaced the Electric Throttle Control Actuator (Motor) to repair the problem.



There is a factory service bulletin for the following Chevrolet models:



2006-2008 Chevrolet Trail Blazer

2007-2008 Chevrolet Avalanche

2007-2008 Chevrolet Express

2007-2008 Chevrolet Silverado

2007-2008 Chevrolet Suburban

2007-2008 Chevrolet Tahoe

Chevrolet Factory Service Bulletin OBDII Code P0507


What does this mean?

When is the code detected?

Thi P0507 code sets when the Powertrain Control Module (PCM) detects an engine speed outside of the Idle Air Control (IAC) valve range of control.

Possible symptoms

- Engine Light ON (or Service Engine Soon Warning Light)

- Engine hard to start

- Rough or erratic idle speed

P0507 Chevrolet Description

The Idle Air Control (IAC) valve is a Powertrain Control Module (PCM) controlled stepper motor located on the throttle body. The stepper motor drives a valve pintle which protrudes into a passage that bypasses the throttle plates. The PCM commands the IAC valve pintle to extend to decrease the idle speed. The bypass air flow is reduced and the idle speed decreases as the pintle approaches its seat. The PCM retracts the IAC valve pintle away from its seat to increase the idle speed. The retracting of the IAC valve pintle allows more air to bypass the throttle plates. One of the PCMs uses for the IAC system is to maintain a desired idle speed. This DTC sets when the PCM detects an engine speed outside of the IAC\'s range of control.

Check engine light appears after 30 minutes of


ON-BOARD DIAGNOSTICS Dodge OBD1 Pre 96

1. Cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds. To cycle the ignition key ON means to turn it only as far as it takes to get the radio to come on. It does not mean to turn the engine on.

2. Count the number of times the "check engine" lamp on the instrument panel flashes on and off. The number of flashes represents the code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual codes. For example, flash-flash-flash [pause] flash-flash represents the code 32.

A code of "55" represents end of error codes. If this is all you get then no error codes are stored in the computer. This is the normal condition

Hi,

Thanks for using Fixya!

1. Cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds. To cycle the ignition key ON means to turn it only as far as it takes to get the radio to come on. It does not mean to turn the engine on.

For example, flash-flash-flash [pause] flash-flash represents the code 32.

A code of "55" represents end of error codes. If this is all you get then no error codes are stored in the computer. This is the normal condition for a neon.
CODE Description of Trouble Code
11 Timing belt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking
12 Direct battery input to PCM was disconnected within the last 50 key-on cycles

55 End of error messages (If you get this only, no errors were found)
62 PCM failure SRI mile not stored
63 PCM Failure EEPROM write denied
64 Catalytic Converter Efficiency Failure
65 Power steering switch failure

So in your case, you are getting error 3255 right? so you are getting error 32 EGR system failure and 55 which is no other error found.

I hope you get this sorted out.
Have a great day sir.

the light has nothing to do with oil or coolant levels. it comes on for one of the following reasons. You will need to have the system computer memory tested to see which fault the system has.

Trouble Code description


Code 46 is indeed the trouble code for the Idle Speed Controller which is that big black box thingy on your throttle body. A lot of Chilton-type manual books omit that code because the ISC isn't found on pre 94 Metros. The ISC is a computer controlled auto-adjuster for the engine idle.

An important note: code 46 is often caused by misadjusted distributor timing. As you probably know, timing affects the idle, and if improper timing moves the idle beyond the ISC's adjustment range, the check engine light will come on and diagnostics will return code 46.
