Tdc code 12 - Pathfinder Nissan Cars & Trucks

Question edited for clarity.

The timing is messed up. Normally it has to be TDC on the Compression Stroke of Cylinder 1. It is a FOUR stroke engine so there are 4 lots of TDC. Or you lock everything using a timing kit, which locks the crank and the cam sprockets..

A P0320 code indicates an issue with the signal that indicates the speed of the engine. This means that the ECM (engine control module) doesn't know where the crankshaft or camshaft is, so it isn't able to distribute fuel or fire spark plugs at the right time.

p0320 Code - Ignition/Distributor Engine Speed Input Circuit

no job stated, so...??
you can't (with a bulb)
but you can watch the piston get to TDC
or set the crank pulley to TDC mark.
you didnt say spark of firing, so cant guess what you are doing
cam
or
spark timing.

keep in mind spark happens only 1 time in 2 TDC events.

P1361 is: Intermittent Interruption In TDC 1 Sensor Circuit.
Check out the TDC sensor, connector 124 (grey and on the distributor) check power and grounds. It's missing a signal from the TDC sensor in the distributor and causing a misfire.

Make sure you are on the compression stroke. At TDC of compression stroke, the rotor should be pointing to number 1 on the cap. Either you are on the exhaust stroke, or the distributor is 180 degrees off and needs to be reset.

check the timing of the ignition as hot exhaust is a good indication of retarded ignition timing. Fire coming out past the exhaust valves because the mixture ha been ignited too late. Have this check out fast as you run the risk of burnt valves . The timing should be about 12 degrees before TDC not 12 degrees after TDC. IT will be the cause of the engine getting hot as well.

6 degrees before TDC

turn engine to TDC No1 cylinder at this point the cam cog has a hole drilling which should be at 12 o/clock position and alignes with a V notch on the cyl head as you look thro the cam drill/hole and when crank pully is at TDC the cog has a marked tooth which should align with mark on engine approx 12-30 pm position these marks are all clear to see and belt change takes around TWO AND HALF HOURS to do

The gap on the points to your distributor is .017 or the thickness of a match book.

there will be two highlighted or dotted chain links for the camshaft and one for the crankshaft gear, position cam dot/TDC indicator in the 12-O clock position, the two dotted links should be on ether side of cam dot, turn crank dot to the 6-O clock position and line up highlighted link with dot on crank gear, if timing cover is on, then make sure cylinder 1 is at TDC when the two links are at 12-O clock.
