- FAULTY INTAKE VALVE TIMING CONTROL SOLENOID VALVE - INTAKE VALVE TIMING CONTROL SOLENOID VALVE HARNESS IS OPEN OR SHORTED - INTAKE VALVE TIMING CONTROL SOLENOID VALVE CIRCUIT POOR ELECTRICAL CONNECTION - FAULTY CAMSHAFT POSITION SENSOR - CAMSHAFT POSITION SENSOR HARNESS IS OPEN OR SHORTED - CAMSHAFT POSITION SENSOR CIRCUIT POOR ELECTRICAL CONNECTION - FAULTY CRANKSHAFT POSITION SENSOR (POS) SINCE THE INTAKE VALVE TIMING CONTROL SOLENOID VALVE USES OIL FLOW TO CONTROL TIMING, DIRTY OIL CAN CAUSE THE VALVE TO STUCK OPEN OR CLOSE. BEFORE REPLACING THE VALVE, CHANGE ENGINE OIL AND FILTER AND RESET ENGINE CODE. WHEN THERE IS A GAP BETWEEN ANGLE OF TARGET AND PHASE-CONTROL ANGLE DEGREE, THE VALVE WILL STOP WORKING AND THE ECM WILL TRIGGER THE P0021 CODE. POSSIBLE SYMPTOMS - ENGINE LIGHT ON (OR SERVICE ENGINE SOON WARNING LIGHT)- LACK/LOSS OF POWER- ENGINE ROUGH IDLE P0021 NISSAN DESCRIPTION THIS MECHANISM HYDRAULICALLY CONTROLS CAM PHASES CONTINUOUSLY WITH THE FIXED OPERATING ANGLE OF THE INTAKE VALVE. THE ECM RECEIVES SIGNALS SUCH AS CRANKSHAFT POSITION, CAMSHAFT POSITION, ENGINE SPEED, AND ENGINE COOLANT TEMPERATURE. THEN, THE ECM SENDS ON/OFF PULSE DUTY SIGNALS TO THE INTAKE VALVE TIMING CONTROL SOLENOID VALVE DEPENDING ON DRIVING STATUS. THIS MAKES IT POSSIBLE TO CONTROL THE SHUT/OPEN TIMING OF THE INTAKE VALVE TO INCREASE ENGINE TORQUE IN LOW/MID SPEED RANGE AND OUTPUT IN HIGH-SPEED RANGE. THE INTAKE VALVE TIMING CONTROL SOLENOID VALVE CHANGES THE OIL AMOUNT AND DIRECTION OF FLOW THROUGH INTAKE VALVE TIMING CONTROL UNIT OR STOPS OIL FLOW. THE LONGER PULSE WIDTH ADVANCES VALVE ANGLE. THE SHORTER PULSE WIDTH RETARDS VALVE ANGLE. WHEN ON AND OFF PULSE WIDTHS BECOME EQUAL, THE SOLENOID VALVE STOPS OIL PRESSURE FLOW TO FIX THE INTAKE VALVE ANGLE AT THE CONTROL POSITION. *TR

I HAVE A 2002 NISSAN ALTIMA 3.5 I BOUGHT NEW. IT HAS 83000 MILES. LIKE OTHERS, MY FLOOR PANS ON BOTH THE DRIVER AND PASSENGER SIDE HAVE RUSTED OUT. I FOUND THIS OUT ON 8/6/14. IT HAS BEEN GARAGE KEPT ALL THESE YRS. I WAS ALSO TOLD IT WAS PROBABLY FROM THE HARSH WINTER AND SALT ON THE ROAD. IF THIS WAS TRUE ALL THE CAR'S IN NJ THIS YEAR SHOULD HAVE THE SAME PROBLEM. I WAS TOLD BY A NISSAN REP. THEY WOULDN'T FIX IT BECAUSE, THERE ARE NO RECALLS ON IT, IT WAS TOO FAR OUT OF WARRANTY, AND I LIVE IN AN AREA THAT HAS A LOT OF SNOW AND SALT. I THINK NISSAN NEEDS TO READ THEIR COMPLAINTS ON THEIR WEB SITE AND STOP SAYING THEY DON'T KNOW ABOUT THIS PROBLEM AND DO SOMETHING ABOUT IT. MY ESTIMATE TO REPAIR THIS IS $2800. I AM ALSO SCARED TO DRIVE IT BECAUSE OF THE SAFETY HAZARD. WHEN I STEP INTO THE CAR IT FEELS LIKE I AM GOING TO END UP ON THE GROUND. I WAS ALSO TOLD IF I GET IN AN ACCIDENT IT COULD BE BAD BECAUSE NORMAL FLOOR PANS HELP PROTECT YOU. PLEASE HELP ALL NISSAN OWNERS WITH THIS PROBLEM. *TR

IF YOU GOOGLE 2002 NISSAN ALTIMA PROBLEMS YOU WILL SEE HUNDREDS IF NOT THOUSANDS OF PEOPLE COMPLAINING FROM ABOUT 60K TO 100K ABOUT A DESIGN FLAW OF HAVING THE PRE CATALYTIC CONVERTER TOO CLOSE TO THE EXHAUST VALVES. THE PRE-CAT WAS FOUND TO BE A PROBLEM OF BREAKING DOWN THE METALS INSIDE AND CAUSING THEM TO BE SUCKED INTO THE ENGINE AND RUINING THE PISTON RINGS AND ULTIMATELY BLOWING THE ENGINE. NISSAN HAD SAID MY CAR WAS NOT PART OF THAT RECALL BUT LOW AND BEHOLD I EXPERIENCE THE SAME SYMPTOMS. 2 QUARTS A WEEK OIL CONSUMPTION, SMOKE COMING OUT OF THE TAIL PIPE, NO HEAT UNTIL ABOUT 4K RPM. MANY CALLS AND COMPLAINTS WENT UPON DEAF EARS. WHY IS IT SO HARD FOR THEM TO SEE THAT THEY MISSED SOME ON THIS RECALL. MANY WITH THIS ENGINE LIKE SENTRA'S WITH THE 2.5 ENGINE HAVE THE SAME PROBLEM. SOME HAVE REPLACED THE PRE-CAT JUST TO HAVE IT FAIL AGAIN AND RUIN THE ENGINE AFTER REPAIRS. *TR
