Test Requirements 

Ensure battery is okay. Ensure all fuses are okay, battery voltage is at least 11.5 volts and fuel pump relay is 
okay. Ensure all electrical accessories are off and A/C is off.  

Test Procedure 

1. Fill fuel tank with 91 RON gasoline. Check knock sensor harness connectors for corrosion, damage and 

proper installation. Loosen knock sensors and tighten to 15 ft. lbs. (20 N.m). Erase DTC memory. 
Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE . If DTC(s) do not 
reset, test is complete. If DTC(s) resets, go to next step.  

2. Check engine for mechanical noise, repair as necessary. If no mechanical noise is found, go to next step. 

If repairs were made and mechanical noise eliminated, erase DTC memory. Perform ECM relearn 
procedure. See TEST DRIVE RELEARN PROCEDURE . If DTC(s) do not reset, test is complete. If 
DTC(s) resets, go to next step.  

3. Turn ignition off. Disconnect knock sensor No. 1 and 2 harness connectors. Check resistance between 

contacts at each knock sensor, resistance should be infinite (no continuity). If no continuity is present in 
resistance reading, go to next step. If continuity is present in resistance reading, replace faulty knock 
sensor(s). Erase DTC memory. Verify repair. Test is complete. Perform ECM relearn procedure. See 
TEST DRIVE RELEARN PROCEDURE .  

4. Turn ignition off. Disconnect ECM harness connector. Leave ECM disconnected from test box. Connect 

Test Box (VAG 1598/31) to ECM harness connector. See CONNECTING VAG TEST BOX . Using 
DVOM, check resistance between the following knock sensor harness connectors and VAG test box 
sockets. Check wiring for short circuit to one another in Knock sensor No. 1 (G61) harness connector. 
Check wiring for short circuit to one another in Knock sensor No. 2 (G66) harness connector. See 
KNOCK SENSOR HARNESS CONNECTOR/TEST BOX SOCKET IDENTIFICATION table. See 
Fig. 33 . Resistance should be a maximum of 1.5 ohms. If wiring is okay, go to next step. If wiring is not 
okay, repair as necessary. After repairs, erase DTC memory. Verify repair. Test is complete. Perform 
ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE .  

5. Erase DTC memory. Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE 

If DTC(s) reset, replace faulty knock sensor(s). After repairs, erase DTC memory. Verify repair. Test is 
complete. Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE .  

DTC P1335/17743 & P1336/17744: ENGINE TORQUE MONITORING 

Code Definition 

DTC P1335/17743 
Engine Torque Monitoring 2 - Control Limit Exceeded 

DTC P1336/17744 
Engine Torque Monitoring - Control Limit Exceeded 

NOTE:

To ensure knock sensors perform perfectly, it is extremely important that knock 
sensors are tightened to 15 ft. lbs. (20 N.m). Contact surfaces between knock 
sensor and cylinder block must be free of corrosion, dirt and grease.
