Attention: TDR Forum Junkies For the last 4 months the check engine trouble light has intermittently lighted and gone off. The periods between on and off have ranged from a couple of days to a month or more. The trouble code on the odometer has always been P1693.
I took the truck to a Dodge dealer today, for the first time, to have the problem checked. Here is their analysis. "Found code in ECM P0336 crankshaft position sensor signal. Tested, found bad crankshaft position sensor and cam position sensor. Estimate for repair $331. 00. "
I noticed in my Haynes Repair Manual that the crankshaft position sensor (CKP) is located by the engine starter and the Camshaft position sensor (CMP) is located up by the injection pump. Although their locations shouldn't make any difference, is it logical that both sensors would go bad at the same time? Why would the technician site code P0336 which only pertains to the CKP and leave out any codes pertaining to the CMP if it too is bad? Does it make sense that a device which senses a magnetic impulse can be defective sometimes and than go for a month without malfunctioning?
The service manager says the engine starter has to be removed to change the CKP. Is that true or is there enough handroom there to remove it without taking the starter out and not bust up the knuckles? How long should it take a novice to do this job?
What about the estimate? Is $331. 00 way more than it should cost?
Finally, if the problem is one or both of these devices, shouldn't there be some noticeable effect in the way the engine runs? So far, it hasn't skipped a beat.
