I somehow forgot to bolt the CAS in place durring my timing belt install . After finally getting the tensioner adjustment right from dozens of trial and error efforts, when it came time to bolt everything back together I flat out overlooked the darn sensor because it was in place, just not bolted up, and spending so much time adjusting the tension I was distracted (it took at least a six pack to get the tension right).

So when it came time to crank the engine when everything was finished - No ignition! I check the connector behind the rocker cover hoping it was off - nope, so it has got to be the sensor since I can't remember bolting that sucker back up or setting the torque wrench to the stated value - I had to have missed it. The SES and brake lights remain on after 20 seconds with key on and figure probably the CAS fault.


My question is is there a way to get to the sensor and bolt it up with minimal disassembly?

I am thinking I can gain access to it by removing the accesory belt and drive pulley, then cutting a small hole into the plastic cover so I can get to it without removing all the stuff needed to get the cover off. After mounting the sensor I can place a patch on the cover. What do you think?

 

how ironic, a customer called me last night about their car not starting after they installed cams, walbro and loaded my flash all in one shot. Sure enough, the fuel pump wasn't doing anything. I bet they forgot the sensor too.

 

Their case would be cam sensor right?.

There is also a chance that the sensor IS hooked up and I am just thinking that I forgot, I guess it could also be the alternator.

When I turn key to IGN the SES is supposed to go out after 20 (I think) seconds but remains on, but I also get a brake light when brake is not ingaged. The brake warning light and generator malfunction light are wired parallel behind the ign switch ECM and alternator. I wonder if the alternator is zapped and the ECU is preventing ignition. Anyone familiar with the symptoms of alterator failure?

 

Can someone do me a favor by the following test?

1. Disconnect your crank sensor connector (the only connector behind the right aft rocker cover).
2. Turn the ignition to "start" for one rotation then back to "off"
3. Turn ignition to "on" and wait 30 seconds

Your SES light should remain on after 20 sec but my real question is do you get a brake light with parking brake off?

When done reset battery

This will help me find out if it is the CAS not the alternator

Thanks

 

i dont think their is a minimal removal trick for this sensor. I've done it 2 times in 2 weeks lol. You can loosen enough bolts to just pry the lower cover out some and reach the sensor and bolt it in, but just be careful to not break the cover. other then that, it just depends on what position the crank blade is in. You may have to rotate the crank some in order to get the sensor in place.

 

Thanks! Ric

I will try tonight after work and get back with a conclusion

 

Was able to get to the prox sensor and fix it in about 1 hour by remving idler pulley, belt, and drive pulley. It was installed backwards

Car runs now and for the first time in 50,000 miles (life of car) the engine doesn't make a rattling noise with the AC on - balance shaft belt was very loose, probably from the beginning.

I also had lifter tick which was cured by servicing and washing adjusters in diesel

 

good deal, im glad you got it fixed. That sensor is easy to install upside down if you arent paying attention.

 

nice and good info, your experience should help many others

 

is this the sensor on the right side of the eng, by the upper rad hose, i think i put mine in upside down too, i got a p0335 p0340

 

no, that is the cam sensor... the crank sensor is on the other side, under the lower timing belt cover directly to the right of the crank sprocket

 

no its not, the sensor he is talking about it right by the crankshaft bolt

 

i have a p0335 and p0340 codes and replaced my cam position sensor and i still have them what else could be wrong

 

those codes are for both cam and crank angle sensors. Does the car run?

 

Either you drink like a fish, or you need more practice on the 4g! I spent a lot of my time working on honda's, then when I got the evo I made the switch. First time I did the belt it was a PITA. Next time easy
