2008 Pontiac g6 ecm port under the dash, when code reader is plugged in it gives a link error? Any ideas what to troubleshoot


is your code reader "can" ready? the newer cars communicate to scanners using different protocols and your scanner may not have that protocol. have you scanned the vehicle using this scanner before? also check fuses as most manufacturers use the cigaret lighter fuse to power the "dlc" data link connector.

I am looking for port to use OBD II tool I can not seem to find it. Any idea where I can find it?


On GM and Fords it's on the lower left hand corner of the dashboard, underneath the dash. You may have to look closer to find it.
There may be a plastic cap on it concealing it from view.

It should be there:

Diagnostic Link Connector Fig. 1: The OBD-II compliant Data Link Connector (DLC) is located under the driver's side of the instrument panel 91144p39.jpg
Fig. 2: A Tech 1® , or equivalent scan tool must be used to retrieve codes from the 16-pin DLC connector 88254gc8.gif
These vehicles are equipped with a Data Link Connector (DLC) which is the 16-pin connector that you attach the scan tool to read and/or clear Diagnostic Trouble Codes (DTCs). The DLC is located under the driver's side of the instrument panel. prev.gif next.gif

How to change a throttle position sensor on a 94 ford f150 5.0 4x4


How to Replace a Throttle Position Sensor
(DIY & Save up to $135.75 ) - Time: 2.1 hours

Parts:
1. Throttle Position Sensor - $ 55.44

Tools:
1. Scan Tool
2. Screwdriver
3. Multimeter

Procedure:
1. Locate the OBD data link connector (DLC). Refer to your owner’s manual for the specific location.
  • Tip: The OBD-I data link connector is usually located in the engine compartment near the battery or the fuse box. The OBD-II connector (post 1995 cars) is usually located beneath the instument panel next to the steering column.
2. Turn your key to the“ON” position. Do not start the engine.

3. Plug your scan tool into the OBD data link connector. Turn on the scan tool and select the appropriate steps to read the diagnostic trouble code (DTC).

Scanner plugged into OBD-II data link connector.
  • Tip: The OBD-II diagnostic trouble code (DTC) is a 5 character alphanumeric code. The first digit is a letter that indicates the component group, the second digit is OBD mandated or manufacturer specfic, the third digit is a subgroup, and the fourth and fifth digits define the component and basic problem.
  • 4. Locate the throttle position sensor.

Where do i find the dlc plug


PLEASE DON'T FORGET TO RATE!!!! Data Link Connector OBD II Systems use a standardized test connector called the Data Link Connector (DLC). It is located beneath the instrument panel somewhere between the left end of the instrument panel and 12 inches (300 mm) past the vehicle centerline.
The DLC is located out of the sight of vehicle passengers, but should be easily viewable by a technician from a kneeling position outside the vehicle. The DLC is rectangular in design, capable of accommodating up to 16 terminals and has keying features to allow for easy connection. The DCL and Scan Tool connector have latching features that ensure the Scan Tool connector will remain mated when properly connected. Some common uses of the Scan Tool are:
  • To identify and clear any stored diagnostic trouble codes
  • To read the serial data stream information (e.g., PID data)
  • To perform Enhanced Diagnostic Tests (bi-directional Scan Tool)

Pulling the trouble codes using a volt meter.


Self-Test with Analog Voltmeter DTCs will be represented by pulsing or sweeping movements of the voltmeter's needle across the dial face of the voltmeter (Figure 9). A single-digit number of three will be reported by three needle pulses (sweeps). However, a DTC is represented by a two-digit or three-digit number, such as 2-3. As a result, the DTC of 2-3 will appear on the voltmeter as two needle pulses (sweeps). After a two-second pause, the needle will pulse (sweep) three times.
The Continuous Memory DTCs are separated from the Key On Engine Off DTCs by a six-second delay, a single half-second sweep, and another six-second delay.

Using an Analog Volt/Ohm Meter (VOM)
  1. Turn the ignition key off.
  1. Set the VOM on a DC voltage range to read from 0 to 15 volts.
  1. Connect the VOM from the battery positive post to the Self-Test Output pin of the large Data Link Connector (DLC) (Figure 3).
  1. Connect the timing light.
17fa78e.gif Using the Malfunction Indicator Lamp (MIL) No special equipment hookup is required. STI is jumpered to SIG RTN at Self-Test Input (STI) connector and the Data Link Connector (DLC).

Self-Test with Malfunction Indicator Lamp (MIL) During Self-Test, a DTC is reported by the Malfunction Indicator Lamp (MIL). It will flash the "CHECK ENGINE" or "SERVICE ENGINE SOON" light on the dash panel (Figure 10). A single-digit number of three will be reported by three flashes.
However, a DTC is represented by a two-digit or three-digit number, such as 2-3 or three digit. As a result, the Self-Test DTC of 2-3 will appear on the MIL as two flashes, then, after a two-second pause, the MIL will flash three times.
The Continuous Memory DTCs are separated from the Key On Engine Off DTCs by a six-second delay, a single half-second flash, and another six-second delay.
