Can anyone explain what the 236 and 237 codes mean? My truck has been tossing these codes off and on for four months now. I unplugged the map sensor and got just a little better throttle response.

 

<table style="font-size:14" border="1" cellpadding="1" cellspacing="0" width="100%"><tbody><tr bgcolor="70D6AD"><td align="center" valign="top">0236</td> <td align="center" valign="top">MAP</td> <td align="left" valign="top">Turbo boost sensor A circuit</td> <td align="left" valign="top">Uses Inferred MAP signal</td> <td align="left" valign="top">Restricted inlet/exhaust/supply hose or missing hose</td> </tr> <tr bgcolor="70D6AD"> <td align="center" valign="top">0237</td> <td align="center" valign="top">MAP</td> <td align="left" valign="top">Turbo boost sensor A circuit low input</td> <td align="left" valign="top">Uses Inferred MAP signal</td> <td align="left" valign="top">Open, short to ground or 5V, faulty sensor</td></tr></tbody></table>

 

Thanks man! I'll have to check on all the hoses.

 

Is your truck chipped?

 

It is not... At least to my knowledge.
