1998 sidekick sport auto - no key start - push button start

wow you are fast mover like me 50 years ago.
P0123 - Throttle Position Sensor/Switch A Circuit High Input -- Need to adjust yes,
P0102 - Mass Air Flow MAF Circuit Low - Start by cleaning it , sure
P1500 - Engine Starter Signal Circuit Malfunction - Probably because of the external switch and (yes)
P0340 - Camshaft Position Sensor Circuit Malfunction - Probably out of adjustment, bad or OUCH - the PCM
P0505 - IAC Malfunction - Probably gummed up, try to clean

yes 340 is not good, cmp
cmp sensor is in the is on the cam left.
ckp is behind flywheel where no man can get. lucky you ! not bad!

so CMP is far more easy.
many this old leak oil inside and go funky puck kinds is optical too... (partly) and fails easy.
is your CMP on left cam hockey puck " only ?

timing on CMP is here

same with plastic sensor mounted to it (easy fix)

before touching that left cam CMP sensor match mark it first, so timing is not lost.
if it has the plugin sensor on the puck, only that needs to be cleaned first, all the metal fuzz off the end. may do that.

the one with a plastic pull off lid one guy opened that, and found a bad O-ring and the leak cause failure. he found seals and posted them here somewhere. $150 sensor up.
the timing freeze jumper works on this car, and set to 5degree BTDC #1 spark plug. (tricky COPS need spark plug extender to set timing, inductive timing light)

I wouldn't call this 'fast' but I do tend to keep on a steady pace and I obsess.. I'm still making room for it in the shop and fiddle with it after work in the dark. It's been very cold here i Virginia so I spend some time with it and then go back into the warm shop to keep pulling stuff off the other one. I'm trying to pull the wiring harness off and keep it intact and that isn't easy so it's taking longer, The one I'm pulling apart has black plastic interior parts and the new one has gray. I'm switching over to black so the new one sits in the driveway until I can get stuff sorted out.

Now that i pulled the codes I saved them and cleared. I then checked all the connectors. Turns out the cam position sensor connector wasn't fully clicked in.
(A the joys of messing with something others were working on that didn't know what they were doing)

Now I just have

P0123 - Throttle Position Sensor/Switch A Circuit High Input -- Need to adjust yes,
P0102 - Mass Air Flow MAF Circuit Low - Start by cleaning it , sure
P1500 - Engine Starter Signal Circuit Malfunction - Probably because of the external switch and (yes)

And... I have a rear main seal leak, oil in the driveway so no matter what the trans is coming out to replace. And some form of a coolant leak, probably the lower tank. These are moving me closer to pulling the engine and sticking my new one in but I still want to see if I can easily solve these mysteries.

That new scanner is the SHI* !!
