One thing to check is make sure you have a steady 5v to the tps and a constant ground clear the engine computer turn the key on push the gas pedal to the floor about 50 to 100 times if your 5v does not change and you have a good ground and the code returns the tps is bad

Harley Davidson Fault Codes


2005-2008
1- Turn Ignition switch to OFF & Run/Stop switch is to Run.
2- Push odometer reset button in & hold.
3- Turn ignition switch to Ignition and release odometer reset button. Background lighting sould illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word "diag" should then appear.
4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.
5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC's the code will be displayed or the word "none" will appear if there are no DTC's. Push the odometer reset button again to view additional codes if they exist.
7 - Record the codes.
8 - If DTC's are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC's again by repeating steps 1 to 9. If the code is current it will reappear.
9 - Press and release the odometer reset button to continue to the next module.
10 - Turn Ignition switch to OFF.
On models not equipped with a tachometer "No Rsp" will appear when the tachometer identifier is selected.
"No Rsp" will also appear if the run/off switch is in the off position when doing this procedure.

Check engine


Well code 63 says the signal from the TPS is too low. The signal voltage is low when the throttle is closed and high when it is open.
A mechanic would check the reference voltage coming from the computer, and the resistance in the sensor with a meter.

63 code for a 1992 Lincoln town car


Hello,

Code 63 on your vehilce is

Throttle Position Sensor (TPS) signal too low TPS

Check the connections at the TPS sensor located on the trottle body Its located on the trottel body on the opposite side of the accelrator cable linkages. Usually this code means TPS needs replaced.

Hope this helps

Code p0122 and p0123 after changing computer


Hi.

The problem is regarding TPS (throttle position sensor located in throttle body). Both codes are TPS voltage out of range (low and high) If you get both codes at once, then :

TPS may be defective,
wiring to TPS may be shorted to ground.
There may be a problem in the +5V circuit powering the TPS.
There may be a problem with ECU connector.

I need to know what the code 18 and 41 means for 93 Buick Park Avenue Ultra with a 3.8 litre supercharged eng


When fixing codes start with first code first / it dos not always mean that the sensor is the fault ,it could be in the harness / the plug or the ground. and reference signal should be tested , but in this case you most likely could get away with replacing the cam sensor, that would be the Lest expensive and easiest to start with,to git to it you will have to remove the alternator hope this is help full, the other code suggest that it could be the crank sensor , that and the plug for it does fail quite often but first things first feel free to ask if you should have any further questions , Thank you ,

99 Saturn SC1 ''Service engine soon'' light is on.


Did you get the code that triggered the SEL? If you know that, it will be easier to diagnose your problem. You can do it without a tool on the old saturns. Just need a paperclip. :

Use a paper clip to jumper Terminal A and B of the ALDL *Assembly Line Diagnostic Link* which is above your left knee.
Terminal A is an interal ground and is the top right terminal in the connector. Terminal B is directly adjacent and to the left of Terminal A.

Turn the ignition to ON.

All codes are 2 digits between 11 and 99. Codes are displayed on the SES light by flashing the light with short and long pauses to distinguish digits of one code from digits of another. The short pause is used between digits of the same code, long pauses are between codes. Also, each code is flashed three times before going to the next code.

For example, the sequence of code 12 will be: flash, pause, flash-flash, long pause, then repeat 2 times. If Code 12 is not displayed, the self-diagnostic pogram i snot functioning properly.

If only Code 12 is displayed, no system malfunctions have been stored.

Any existing system fault codes are displayed in order from low to high, except for Code 11.

On vehicles with an automatic transaxle and on which exist stored transaxle codes, Code 11 will be displayed last, then the SHIFT TO D2 light will begin flashing transaxle codes of flags.

When all engine codes have been displayed, Code 12 will flash again.

Diagnostic Codes
11. Transaxle Codes present
12. Diagnostic System Check
13. Oxygen sensor, circuit open or not ready
14. CTS circuit, out of range high
15. CTS circuit, out of range low
17. PCM fault, pullup resistor

21. TPS circuit, out of range high
22. TPS circuit, out of range low
23. ATS circuit, out range low
24. VSS circuit, no signal
25. ATS circuit, out or range high
26. Quad Driver output fault
32. EGR system fault
33. MAP sensor circuit, out of range high
34. MAP sensor circuit, out of range low
35. IAC valve, rpm out of range
41A EST circuit open
41B EST circuit shorted
42A Bypass circuit grounded
42B Bypass circuit open
42C Bypass circuit shorted
41. EST bypass, open or shorted
42. EST bypass, open or shorted
43. ECS (knock sensor) circuit open or shorted
44. Oxygen sensor indicates system lean
45. Oxygen sensor indicates system rich
46. Power steering pressure switch circuit, open
49. Idle rpm out of limit high (vacuum leak)
51. PCM memory error
55. A/D converter error in PCM
81. ABS message fault (1993 vehicles with TCS)
82 PCM internal communication fault


Diagnostic Flags
27. Quick quad driver output fault (1993 only)
48. Reference imput intermittent or noisy
52. Battery voltage out of range
53. ESC knock present
54. Five volt reference ground
58. Battery voltage unstable
61. 6x signal fault
63. Option check sum error
67. Handwheel sensor circuit fault
71. Cooling system temperature high
