Problems with 1995 protege 1.5l dohc
Hey my buddy owns a 95 protege with the 1.5dohc.
He's having alot of problems with it and he finally got it towed to my house. I work as a mechanic at NTB so i have alot of broad mechanical experience. But i have little to no experiance with sensors and electrial problems.
Basically if you try to start the car it doesnt start. I sprayed some starting fluid into the intake and started it up. The car ran for a little while. (maybe like 5 minutes?) ran like ****. i had to keep pressing the gas pedal. When I pressed the gas pedal it bearly felt like from the Amount of gas i was giving it it was bearly climing in rpms.
He recently got into a small low speed front end collision. All that seemed to be wrong was the hood was a little dented and the Radiator blew. I changed out the radiator and the car drove fine for over 2 weeks. long and short trips.
All of a sudden one day (he drove the car night before with no problems) he goes to start the car and all the problems happend. check engine light was on and i checked it with my scanner.
codes:
po115 - Engine coolant temp circuit malfunction
po400 - Exhaust gas recirculation flow malfunction
po510 - Closed throttle position switch malfunction
po340 - Camshaft Position Sensor malfunction.
Origianlly i thought the timing belt/tps sensor went hense why i told him to stop trying to start it or touch it and get it towed to my house.
Pulled off the valve cover and timing belt seems great and even close to new. The chain on the camshaft gears seemed fine as well.
Reninstalled valvecover and thats when i started it with the starting fluid for about 5 minutes.
So now im thinking its def. the TPS sensor but what else would make it stall so bad and not want to start?
and wtf is with the camshaft posision sensor.
lol thanks and let me know if anyone has any light on this situation.

Possible, But wouldnt it trigger some kind of MAF code?
What size MAF are those? Any other vehicles that have the same one? I went to one of the largest junkyards in the area and they didnt have many mazda protege's in it. I ended up pulling off the wrong tps sensor. The only 2 mazda protege's in his year didnt have motors in them. lol.
About the timing belt. That would probably effect the car within the first 100 miles of him driving it? After the accident he drove it for like 2 minutes car started smoking he called me I went out there with 2 gallons of warmish water and used it up till i got to my house from there it was only about 10 minutes. Changed radiators next day and after that he had like 2-3 weeks of trouble free driving. Then one morning it just randomly started put in reverse moved like 2 feet and died. Then all the codes came up.
Now its at my house, lol.

Didnt think about the driving after you fixed it so it cant be the timing belt
did you check for water in the oil ? is the head gasket still good ??
Dont know how much I would trust those codes...try clearing them and if you can get it to run again see which ones pop up...
The EGR code doesnt mean crap, car would still run fine
and 3 other sensors going bad at once sounds fishy to me...
sounds like something major

Long shot, guys, but consider this.
I had those exact same symptoms and got several nonsense codes. DID get one about the oxygen sensor which was relevant and you're not getting that.
But the problem I had was simply a small slit on the underside of the flexi rubber part of the air intake hose. Fits between the air cleaner box and the engine.
'95 Protege 1.5 DOHC acted like the engine was blown. Didn't want to start. If you got it to start you couldn't keep it running -- like the timing had badly slipped, and I had to pump, pump, pump, pump the accelerator to keep it running at all, and got NO revving from that.
Part was about $70 at the dealer.
You might want to remove and inspect that really carefully. Could have gotten torn in the accident.
Hope that helps.
Best,
kwc
