EGR Flow Insufficient Detected The EGR system is monitored during steady state driving conditions while the EGR is commanded on.
The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum. Vacuum supply EGR valve stuck closed EGR valve leaks vacuum EGR flow path restricted EGRVR circuit shorted to PWR VREF open to D.P.F. EGR sensor D.P.F. EGR sensor downstream hose off or plugged EGRVR circuit open to PCM VPWR open to EGRVR solenoid D.P.F. EGR sensor hoses both off D.P.F. EGR sensor hoses reversed Damaged EGR orifice tube Damaged EGRVR solenoid Damaged PCM Perform KOER self-test and look for DTC U1682 as an indication of a hard fault.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code U1682, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code U1682 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

U1682 Error Code Repair Process :

If your wiper rear low limit input circuit short to ground check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system U1682 and engine control unit are in charge of monitoring a bunch of different wiper rear low limit input circuit short to ground, and if they get a reading that's a little out of whack, up pops the check engine light.

U1682 is a kind of Network Trouble Code

U-code indicates that engine communication errors and shows lost communication with engine parts.U-Codes are fairly straight forward, given all of the articles and technical publications that have been written regarding these problematic codes. In most cases, it just comes down to identifying the module that isn't communicating with the other modules on the CAN bus line for whatever reason.

Common Causes of U1682

A common cause of code U1682 is the failure of Wiper Rear Low Limit Input Circuit Short To Ground, but there are several other possible causes as well, such as ;

Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Damaged camshaft position (CMP) sensor
Intake Valve Timing Control Solenoid Valve circuit poor electrical connection
Variable Camshaft Timing (VCT) position circuit is open or shorted
