A barrage of DTC's

[Rodd]

I was on a 150 mile round trip yesterday and on my way home my SES light came on. When I got home I checked them and this is what I found.

Diagnostic Trouble Codes
P0126 Insufficient Coolant Temperature for Stable Operations
P0236 Turbocharger Boost Sensor A Circuit Range/Performance
P0269 Cylinder 3 Injector Circuit Contribution/Balance Fault
P1216 Fuel Solenoid Response Time Too Short
P1217 Fuel Solenoid Response Time Too Long

The one that really baffles me is the turbo code. I put on the heath t/m back in july and cleared the code. It hasn't coded until now with everything else. I am going to try and post the freeze frames when it happened. Hopefully it will look okay appearance wise.

someone has to have some idea why I would get these codes all at the same time.

Here is my take.

Diagnostic Trouble Codes
P0126 Insufficient Coolant Temperature for Stable Operations - I was running my heater at the time and it was working fine. This one is the most confusing of them all.

P0236 Turbocharger Boost Sensor A Circuit Range/Performance - Like I said in my previous post I have a heath t/m and it hasn't had a problem till now.

P0269 Cylinder 3 Injector Circuit Contribution/Balance Fault - What could this be?

These next 2 are IP codes. I know that low quality fuels can cause both these codes.
P1216 Fuel Solenoid Response Time Too Short
P1217 Fuel Solenoid Response Time Too Long

Rodd,

I hate to start with this, but make sure your battery cables and grounds are clean and tight. I had a boost sensor go bad and I got the same code you are getting intermittently. I troubleshot all over and the main cause of my DTC's was the dirty cables.

 

[Rodd]

Grounds are on my list of things to do. I guess those will get done first.

C-time seems to be a little high, i'd clear codes and check it again.

 

[Rodd]

Maybe I overlooked it. What is C-Time?

Thanks!

C-time seems to be a little high, i'd clear codes and check it again.

As i understand its the selonoid closure time in the IP, prior to 96 i believe it would set a code on OBDI above 2.20ms. Not sure where it sets a code on OBDII. Also i've heard the more current draw you have the higher the C-time, haven't seen it myself though. Its something i always watch when i have my scanner hooked up.

 

[chrisk1500]

High current draw, bad connections, poorly made extension harness, failing PMD, failing fuel solenoid will all give high C-Times....

-1.8 is a nice time to aim for....

What's confusing? Your snapshot shows 126 F coolant temp. Either your CTS has a bad ground or the sensor is wonky.

P0236 Turbocharger Boost Sensor A Circuit Range/Performance - Like I said in my previous post I have a heath t/m and it hasn't had a problem till now.

The sensor (or the circuit that it grounds on) can still be bad. The TM gives you boost, the sensor senses the boost. If the sensor circuit is bad the ECM will throw a code.

P0269 Cylinder 3 Injector Circuit Contribution/Balance Fault - What could this be?

Could be anything - dirty injector, IP hiccup. Watch this code to see if it comes back.

These next 2 are IP codes. I know that low quality fuels can cause both these codes.
P1216 Fuel Solenoid Response Time Too Short
P1217 Fuel Solenoid Response Time Too Long

Grounds/current/solenoid/PMD


Got the hint yet?


If the grounds ain't happy - nobody's happy....
