For some reason, when i installed my tbe, i never got a check engine light so i thought everything was okay and drove on. However, today when I got in my car and turned it in, the check engine light came on and the rpm's shot up to 2500~ It sloooowly came down to normal after 10-15 seconds.

I was in a rush to get somewhere so i got in and drove off. By the time I got onto the highway my temperature was warmed up and at normal temperature. I was on 5th gear on the highway cruising for a minute or two when the engine bumped down the rpm. I want to say it stuttered, twice. This scared the hell out of me, but it kept cruising fine so i drove on, got to my destination and returned home safe.

As soon as I got home I plugged in the accessport and it gave me these codes:

• P0102 - MAF Sensor
• P1518 - Starter switch circuit low input
• P0851 - Park/Neutral sensor
• P1153 - O2 Sensor Circuit Range/Performance (Low) Bank 1 Sensor 1
• P1152 - O2 Sensor Circuit Range/Performance (High) Bank 1 Sensor 1
• P0137 - Second oxygen sensor

I looked these up on the interweb, so please let me know if they are wrong.


I'm pretty sure I'm not supposed to have this many errors.. is my car about to blow up? What is going on? What do i do? Just clear them all on the Accessport and should it be all good?

Thanks for any help,

Kevin

 

check your blinker fluid. it may be too high

 

Here's what I would do, I would check the green connectors if that's connected (use with ap for flash), sensors around tranny, maf sensor, 02 sensor in the rear, grounds, and etc. Just back track and check everything.

My check engine light turned on when the connectors were not connected, obviously because i've been driving couple thousand miles fine.

but I did plug the green connectors and white connecter (2005) when i plugged in the accessport. did i not have to to see the codes?

 

Umm.. sorry for my lack of understanding but did you recently plug in the connectors? If these plugs are connected the car would go in limp mode and it will throw lots of cel codes. No need to plug the connectors in to check codes if the ap is already married to the ecu. Clear all the codes and see what happens.

Ron

 

The car is now giving no check engine light. What the heck is going on....?

I'll try clearing the codes. Does clearing codes solve the problem or just hide the problem from showing through the codes?

 

did you disconnect the battery and hook it back up so it can reset to all the new mods??

 

Those codes will put your car on limp mode. Drive it for a bit and see if it pops out again. If not you should be good to go.

The only time the green connectors should be plugged together is when your conducting either a reflash or basemap flash (AP2 or AP1).

If you have some time either tomorrow or Saturday afternoon I would be happy to double check everything for you.
