NO ENGINE TOLD AT ALL
2002-2009 LL8 4.2 L I6
2005-2009 LH6 5.3 L V8
???????????????????????? MATTERS.
did you buy the car used and in broken state?
replacing sensors blind (guessed) invites relearn H3LL.
you can clear the codes 10 times a day, no damage.!!!!@
it only clears history memory logs on all stored DTC ERRORS.
if the DTC COME back those ARE REAL and NOW. LIVE error.
Codes p0304 p0526 p0335 p0445
304 means combustion is weak on cylinder 4 ( 3BASE CAUSES)
526 = ENGINE RAD COOLING FAN PROB.
335 = Crankshaft Position Sensor ,, VERY SERIOUS THIS FIX FIRST
445 =EVAP VENTS FAIL, FIX DEAD LAST;
(BASE: COMPRESSION ,SPARK ,FUEL) FOR
304 CYL, 4 MEANS SPARK LOST, INJECTOR FAILS OR COMPRESSION FAILS OR EVEN INTAKE AIR LEAKS TO #4 INTAKE PORT. OR A LIE, DUE TO 335, FOR SURE 335 CKP IS INTERMITTENT AND IT MUST BE, AS IF WAS DEAD SPARK ENDS.
FOCUS ON 335, IF IT REPEATS FIX IT.
304 CAN EVEN BE WATER LEAKS TO INTAKE PORT #4
OR EVEN CRACKS IN THE HEAD. TO #4
335 TRY A NEW SENSOR
READ THE SERVICE MANUAL FIRST ON CKP 335 AND SEE IF THE SENSORS MUST BE ADJUSTED OR SHIMMING
OR MUST BE RELEARNED (
YES)
TO START A RELEARN, PULL BATTERY NEG LUG FOR 1HR.
THIS WILL FORCE ALL RELEARNS or the text large below.
QOD:
YOU PUT IN 6 OR 8 NEW COP SPARK COILS?
YOU SAID COIL, SINGULAR, #4 SURE.
BUT THE V8 HAS 8 COIL PACKS AND V6 HAS 6.
im trying hard to glean what engine is there and I FAIL.
OK im reading YOUR SM service manual and doing global search there
LEARN in 3 seconds fast I see warnings on CKP
The crankshaft position (CKP) system variation learn procedure is required when the following service procedures have been performed, regardless of whether DTC P0315 is set: or 335
- Engine replacement
- Engine control module (ECM) replacement
- ECM reprogramming
- Crankshaft damper replacement
- Crankshaft replacement
- CKP sensor replacement
- Any engine repairs which disturb the crankshaft to CKP sensor relationship
ok now the relearn steps in your manual not read by you, I guess
Install a scan tool.
Monitor the ECM for DTCs with a scan tool. If other DTCs are set, except DTC P0315, refer to Diagnostic Trouble Code (DTC) List - Vehicle for the applicable DTC that set.
quote learn mode. pasted.
"With a scan tool, select the CKP system variation learn procedure and perform the following:
3.1.
Observe the fuel cut-off for the applicable engine.
3.2.
Block the drive wheels.
3.3.
Set the parking brake.
3.4.
Place the vehicle's transmission in Park or Neutral.
3.5.
Turn the air conditioning (A/C) OFF.
3.6.
Cycle the ignition from OFF to ON.
3.7.
Apply and hold the brake pedal for the duration of the procedure.
3.8.
Start and idle the engine.
3.9.
Accelerate to wide open throttle (WOT). The engine should not accelerate beyond the calibrated fuel cut-off RPM value noted in step 3.1. Release the throttle immediately if the value is exceeded.
important: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is returned to the operator and the engine responds to throttle position after the learn procedure is complete.
Release the throttle when fuel cut-off occurs.
turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.?? unquote
