Question about 1997 Ford Ranger SuperCab

1 Answer

Smog failed cause cam sensor

Replaced cam sensor checked that crank & oil pump gear were correctly timed still recieving 340 code. truck is a 97 2.3 with 267,000 + runs great. I did replace the timming belt 2 years ago @ aprox. 175,000 cause I didn't want to posibly have a big problem. My personal openion is this cam sensor is BS, the cam gear could be any place & the cam sensor wouldn't know cause it runs off the oil pump gear.I checked for wires bad conections & there are no visable signs of wear.

    How the h... does the thermostate or catalytic converter have any thing to do with an auto trouble code 340 which indicates a bad cam sensor! Did you send a fixit statement to the wrong person?

You should check the make sure the thermostat operates normally and that the fuel octane is 87 or higher (usually the lowest grade available at the station, so I doubt this is the issue). If your engine temperature isn't too high and the fuel is 87 octane or more, I'd expect you probably have a catalytic converter issue

What might cause codes p0325 , p0304 to turn my check engine light on during smog test on my1998 Nissan Altima 2.4L No kicking No noise except the drive belt which just started after smog test


This is common in the Nissan's could be the cam and crank sensor these go at around 70000 to 120000 should do both at once to be safe. that will fail an emissions test for sure. hope this helps

What does this code mean


Does the truck run ok? If so may just be bad sensor .it reads the correlation between cam and crank shafts so timing is correct so the camshaft control the valves and crankshaft controlling the pistons don't hit each other

Code p1391


You could've gotten dirt or grease inside the cam sensor connection. They are real fussy.

Passing smog


code p 1340 refers to crank position sensor and camshaft position sensor signals out of sequence
the results of the pretest smog test at 2400 rpm suggest that the cam advance solenoid or system is failing
that will alter the sequence of the signals resulting in the code and failing of the smog test
as to answer you question , I am not convinced at this point but I consider the cam advance system to be at fault and would be testing in that area

Passing smog


I doubt it as you have stated that it shows a calibration fault . This will be from the variable valve timing assembly on the cam shaft/s that is altering the valve timing. The timing chain may be faulty but you should be hearing it to be that bad.

95 Mazda b2300 2.3: will a bad cam position an a bad crank position sensor make my truck not start? Also will a lil bit of oil on the cam position sensor cause it to go bad?


You seldom have both sensors fail at the same time.
Either one could keep the truck from starting.
You should have a trouble code for one of them if they have failed.
As for fuel, do you know you are getting power to the pump ?

97 CAVALIER (Z24) FAILED SMOG TEST


No the water pump will not affect the smog test. You probably failed the idle?
Usually with this age of vehicle you can replace the o2 (oxygen) sensor and it will pass. Cleaning the MAF if it has one cant hurt either if you do it right.

98 dodge stratus,engine light came on and it died and won't start now.What could be wrong?


when you crank the engine over now, does it sound different than before? if yes, you probably have a broken timing belt. it is also common for the cam gear to slip out of position from the cam and cause an incorrect, but hard to diagnose, timing issue. other no start with check engine light on issues could be a faulty cam or crank sensor.

pull the codes from the vehicles computer. if there is a cam or crank sensor code, or if there is a code that says in some different wording "cam sensor signal does not match crank sensor singal", first check crankshaft to camshaft timing. if belt is ok and timing marks line up then i strongly suggest removing the bolt from the camshaft that holds the cam gear on. with the bolt and cam gear removed you should be able to tell if the cam gear has rotated on the camshaft. there should be a small pin sticking out of the camshaft. if it is broken off then you need to replace the camshaft. if the pin is still there and the timing is good then replace iether the cam or crank sensor depending on what code you have stored in the ecu memory. if the code is not for the cam/crank sensor then google search the code number e.g. "p0502" and your make and model.

How to you install a water pumpon a 3.5 97 dodge


Remove the hood bracket bar, 4bolts, then the fan shroud assembly, then the belts, belt adjuster, and timing covers, line up the cam gears, crank gear to the marks , cam has 1 dot, they line up to timing housing 2 dots, (single dot to middle of the 2 dots), crank has 1 dot to mark on the oil pump housing to your right of crank gear, thats TDC. now remove the timing belt tensioner, 2 bolts, and remove the belt, if the pump has leaked, replace the belt, and tensioner if it is NOT metal Pulley, the fibre one will break down from the antifreeze. its a good idea to replace the water pump housing orings behind it, ac bracket has to come off, as the right cam on engine, this not a retiming iussue with the gear. GOOD LUCK. RDJRP
