PO135 is oxygen sensor Bank1 sensor1. PO404 is EGR.
personally, I'd pull EGR off, clean pintle good with throttle body cleaner or carb cleaner, re-install, erase codes & try it for a while & see if it code(s) come back.

SOURCE: 94 Cadillac DeVille: Car would only run for 20

When the car has the crank/no start, at that point see which is missing. Test for fuel and spark. I think it has to do with fuel, a tired fuel pump or relay. But remember to check the oil sending unit. If it fails it will shut down the fuel system.

SOURCE: my 2001 cadillac deville keeps giving me dtc code system to lean

Anytime I get a too lean DTC I first change the fuel filter if it hasn't been changed in awhile. You'd be surprised how many times this has helped.

Good Luck with it.

I have a p1336 code. is it a bad sensor or a wire problem ?


This is from updated GM service manual of mine.


According to the GM factory service manual, the OBD-II trouble code, P1336, is defined as follows: DTC P1336 CKP System Variation Not Learned. The factory service manual does not enumerate all of the symptoms of this trouble code, but after consulting a professional custom PCM tuner, it was learned that aside from the annoying light on the instrument cluster, the other symptoms exhibited may include: poor vehicle performance, and loss of misfire detection diagnostics.


This DTC is particularly nasty, because simply clearing it by disconnecting the battery, or clearing it using an OBD-II scan tool will not address the problem. The code will be set again later unless the vehicle is run through the actual "crank relearn" procedure.


Fixing the Dreaded P1336 DTC


There is only one way to properly fix the P1336 DTC, and that's to perform a "crank relearn" procedure, or as the GM factory service manual procedure calls it, the CKP System Variation Learn Procedure. This procedure can be initiated and performed by GM's be-all end-all scan tool, the Tech-2. It can also be performed by some aftermarket scan tools. Furthermore, some of the PCM tuning software applications are capable of initiating a "crank relearn" procedure.

Just did a tuneup new wires and plugs how do I


Turn the key on. Hold off and warmer on the climate control until all the lights light up. It will now read out all the codes in all the computers. Let it go until it reads (PCM?). Now push up on the blower speed. It will read PCM DATA. Now push down (I think 3 times) until it reads CLEAR CODES. Now push up on the blower speed. It should read PCM CODES CLEARED. Now turn the key off.
