Check engine code meanings
Hey gents I jumped the two terminals on the engine diagnostic plug and got 11 different codes. The codes are :
32, 33, 36, 29, 46, 35, 73, 84, 87, and 99
Can someone tell me what they mean and how to fix them

When you have that many codes it is often a problem with a bad ground.
Make sure that the 3 grpound wires fastened to a stud at the back of the engine on the passenger side are crystal clean and tight.
If they are in the stock location it may be 1 wire with a ring terminal and 2 wires that share a ring terminal-it's ok to separate them when a repair is made.
the stud they are fastened to from the factory is the coolant block off plate stud so if it turns,don't be surprised if you get a coolant leak,seal the threads when you fix it.
If it has been apart don't be surprised if they are moved to an intake stud-it's better if they are on the block off plate stud though.
Also don't be afraid to add a ground wire from there to the drivers side battery ground.
DTC 29 - Glow Plug Relay Fault
DTC 32 - EGR Circuit Error
DTC 33 - EGR Control Pressure/Baro Sensor Circuit High
DTC 35 - Injection Pulse Width Error (Time Short)
DTC 36 - Injection Pulse Width Error (Time Long)
DTC 46 - Malfunction Indicator Lamp (MIL) Circuit Fault
DTC 73 - Pressure Control Solenoid Circuit (Current Error)
DTC 84 - Accelerator Pedal Position Circuit Fault
DTC 87 - Transmission Gear Ratio Error
DTC 99 - Accelerator Pedal Position Sensor 5-Volt Reference Problem
With the variety of codes I would concentrate on those grounds first.

Well I cleaned the stud and the nuts and replaced the ring terminals and the CEL is still on. I even disconnected the batteries after I did it for about a minute. I havent checked all the codes but I will this afternoon and see if I fixed anything
Need a wiring diagram that shows the ground for those sensors,most codes shown probably share a ground,except for the IP codes.
DTC 62 - Turbo Boost Sensor Circuit Low
The IP codes can sometimes be caused by a failing PMD but not always,or the IP is on it's way out?

I cleaned the grounds on the back of the engine. Where are the other grounds? I also checked all of the fuses, all were fine.

Alright I have good news. I disconnected all of the cables and let it sit for a bit. Cleared the codes and took it for a 10 minute drive after I let it warm up for 10 mins. The only codes that came up were 33 and 35 both EGR... I see and EGR delete in my future.
