(11)--"A"camshaft position timing over-advanced or system performance bank 1++ ( 21)-- "A"same as above but bank 2 ++(24)--"B" same as above but bank 2=== check ur wiring and connections to ur oil control valve and solenoid and power control module also check ur v v t/v c t variable valve timing /variable camshaft timing circuits
Code 11. Engine hasn't been cranked since last reset - Power was removed from the logic module (disconnected or dead battery, etc.) and the logic module has no memory of seeing a signal from the ignition reference sensor. Crank the engine and check for the code again. If the logic module saw a signal, the code will be cleared. This code will not show up if the sensor simply fails. The logic module must be reset and the engine cranked to see if the sensor is working.
code 21.Bad connection or wiring - Check the wiring and connections between the sensor and the logic module (or SMEC). Clean and regrease any corroded connectors with dielectric grease and repair any shorts. Look for melted wire insulation near the exhaust manifold. An open connection will cause this fault code.
Bad oxygen sensor - Replace the sensor which is located on the turbo housing near the down pipe (for turbo) or on the down pipe near the exhaust manifold.
code 24.TPS failure - The TPS is located on the throttle body on the opposite side of the throttle cable. Turn the engine off, disconnect the sensor and test it by connecting an ohmmeter (preferably an analog one) between the center and either outside pin of the sensor. Slowly open the throttle all the way and then slowly close it again. The ohmmeter should show a constant, smooth change in resistance as the throttle is moved. If there are any jumps in reading or no change in reading at all, replace the sensor. If the sensor seems ok, reconnect the sensor cable and turn the ignition on. One outside wire should be 5V, the other ground. The voltage on the center wire should vary as the throttle is opened (about 0V closed, 3V wide open). If power or ground is not present, check the wiring.
Bad connection or wiring - Check the wiring and connections between the sensor and the logic module (or SMEC). Clean and regrease any corroded connectors with dielectric grease. Check connections if there is no power or ground, or for shorts if there is power and resistance, but no output.
