судя по нашему поиску ты первый с такой ошибкой. вполне возможно что придется обратно снимать блок предов и проверять, могло что то сгореть. и проверь преды в салонном блоке.

Все неправильно, или почти все.

DTC P1682: DRIVER 5 - LINE 2
Circuit Description
The Electronic Throttle Control (ETC) system uses an ignition voltage supply separate from the Engine Control
Module (ECM) supply. If ECM detects a voltage difference between the 2 circuits, this DTC will set.
Conditions For Running DTC
Ignition is on.
Conditions For Setting DTC
ETC ignition voltage is less than 10 volts for greater than 10 seconds.
Action Taken When DTC Sets
NOTE: To locate components, see COMPONENT LOCATIONS . For circuit reference,
see ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS article in
ELECTRICAL. For connector terminal identification, see CONNECTOR
IDENTIFICATION .
? The control module stores the DTC information into memory when the diagnostic runs and fails.
? The Malfunction Indicator Light (MIL) will not illuminate.
? The control module records the operating conditions at the time the diagnostic fails. The control module
stores this information in the Failure Records.
? The driver information center, if equipped, may display a message.
Conditions For Clearing MIL/DTC
? A current DTC Last Test Failed clears when the diagnostic runs and passes.
? A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other
non-emission related diagnostic.
? Clear DTC with a scan tool.
Diagnostic Procedures
1. Perform diagnostic system check - engine controls. See DIAGNOSTIC SYSTEM CHECK - ENGINE
CONTROLS under SELF-DIAGNOSTIC SYSTEM. After performing diagnostic system check - engine
controls, go to next step.
2. Observe the Freeze Frame/Failure Records data for this DTC. Turn ignition off for 30 seconds. Turn
ignition on, with engine off for 10 seconds. Does the DTC fail this ignition? If yes, go to next step. If no,
problem is intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES - 2.2L &
3.0L VUE article.
3. With a test light connected to ground, probe both sides of the ETC fuse. Does the test light illuminate on
both sides of the fuse? If yes, go to step 5 . If no, go to next step.
4. Does the test light illuminate on one side of the fuse? If yes, go to step 6 . If no, go to next step.
5. Turn ignition off. Disconnect ECM. Test both ETC ignition circuits for an open or for a high resistance.
Did you find and correct the condition? If yes, go to step 9 . If no, go to step 7 .
6. Turn ignition off. Disconnect ECM. Test both ETC ignition circuits for a short to ground. Replace fuse, if
necessary. Did you find and correct the condition? If yes, go to step 9 . If no, go to next step.
7. Test for an intermittent and for a poor connection at ECM. Did you find and correct the condition? If yes,
go to step 9 . If no, go to next step.
8. Turn ignition off. Replace ECM. Perform ECM relearn procedure. See ELECTRONIC CONTROL
MODULE REPROGRAMMING under PROGRAMMING. After replacing ECM, go to next step.
9. Using scan tool, clear DTCs. Turn ignition off for 30 seconds. Operate vehicle within the conditions for
running the DTC. See CONDITIONS FOR RUNNING DTC . You may also operate vehicle within the
conditions observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition? If yes, go to
step 2 . If no, go to next step.
10. With a scan tool, observe the stored information, Capture Info. Does the scan tool display any DTCs that
you have not diagnosed? If yes, see DIAGNOSTIC TROUBLE CODE DEFINITIONS . If no, system
is okay.
DTC P1516: THROTTLE ACTUATOR CONTROL MODULE - THROTTLE ACTUATOR POSITION
PERFORMANCE
Circuit Description
The commanded throttle position is compared to the actual throttle position. Both values should be within a
calibrated range of each other. The Engine Control Module (ECM) continuously monitors the commanded and
actual throttle positions. If ECM detects that the difference in these values are greater than the calibrated range,
DTC 1516 will set.
Conditions For Running DTC
? Ignition is on.
? Ignition voltage is greater than 8 volts.
? System is not in Battery Saver Mode.
? Engine is running.
? DTC P1514 is not set.
NOTE: To locate components, see COMPONENT LOCATIONS . For circuit reference,
see ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS article in
ELECTRICAL. For connector terminal identification, see CONNECTOR
IDENTIFICATION .
Conditions For Setting DTC
The difference between the predicted and the actual throttle position is greater than a calibrated amount.
Action Taken When DTC Sets
? The control module illuminates the Malfunction Indicator Light (MIL) when the diagnostic runs and fails.
? The control module records the operating conditions at the time the diagnostic fails. The control module
stores this information in the Freeze Frame and/or the Failure Records.
? The control module commands the TAC system to operate in the Reduced Engine Power mode.
? Under certain conditions the control module commands the engine off.
? The message center displays Reduced Engine Power.
Conditions For Clearing MIL/DTC
? The control module turns off the Malfunction Indicator Light (MIL) after 3 consecutive ignition cycles
that the diagnostic runs and does not fail.
? A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
? A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other
emission related diagnostic.
? Clear MIL and DTC with scan tool.
Test Description
The numbers below refers to the step number in the diagnostic procedures.
1. 8 - The throttle valve is spring loaded in a slightly open position and should move in either direction
without binding. The throttle valve should always be under spring pressure.
2. 11 - When ignition is turned on, the ECM operates the throttle control motor to verify the integrity of the
system prior to start-up. This can be seen by the momentary flash of the test light as the ignition is turned
ON.
Diagnostic Procedures
1. Perform diagnostic system check - engine controls. See DIAGNOSTIC SYSTEM CHECK - ENGINE
CONTROLS under SELF-DIAGNOSTIC SYSTEM. After performing diagnostic system check - engine
controls, go to next step.
2. Are DTCs P1120, P1220, P1221, P1271, P1275 and P1280 also set? If yes, diagnose affected DTC(s).
See DIAGNOSTIC TROUBLE CODE DEFINITIONS . If no, go to next step.
3.
Turn ignition on, with engine off. Observe the TP sensors No. 1 and 2 angle parameters. Apply and
NOTE: The throttle angle and pedal angle may not correspond during this
procedure.
release the accelerator pedal several times. Does the TP sensors No. 1 and 2 angle parameters increase as
the pedal is applied and decrease as the pedal is released? If yes, go to next step. If no, go to step 5 .
4. Observe the Freeze Frame/Failure Records for this DTC. Start engine. Operate the vehicle within the
Conditions for Running the DTC. See CONDITIONS FOR RUNNING DTC . You may also operate
the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. Did the DTC
