Throttle Position Sensor/Throttle Body
2004 Maxima SE, 48K miles.
A SES light came on and it stalled out a few minutes after startup, restarted ok and no issues since. Went to Autozone, pulled code P2135 (TPS Sensor) and took it to dealer (Nooooo!) They say it is the EFI Throttle Chamber i.e. Throttle Body Unit. Does this sound correct? Anyone had to change out that could give me advice on R&R. Dealer wants 350 for reman. part/labor I found salvage complete unit for 85. Any help would be greatly appreciated. |

Re: Throttle Position Sensor/Throttle Body
Had throttle body replaced with a remanufactured part last week and now I get an SES light on. Noticed a high idle over the weekend and then the light. AZ scanned and it was a high rpm/idle code. I reset by disconnecting neg bat cable for 5 min but did not clear light. Any suggestions??

Re: Throttle Position Sensor/Throttle Body
Use CRC electronic cleaner for connections, the throttle body probably needed a good cleaning.
A 2004 with 48K miles isn't very many miles. Picture a Briggs & Stratton engine setting all winter long, and expecting no problems in the spring. It's one cylinder + 4 strokes to get it right! ''fire'' |

= read em... Typically ECU resets after batt off (blckout) after 30min or more. That clears all accumulated data used in engine ctrl, wont hurt too much.

Re: Throttle Position Sensor/Throttle Body
Tried the neg. cable trick for at least 45 min but SES light still on and high rpm (1100-1500) at idle and in gear. Prob have to take back to shop to have them check out if no further advice from you guys! Any ideas?

2 Throttle/wire zero adjustment not done. 3 The spare part is defective. Never swap b/c warn light blip - $tealerships love your wallet. Check/correct zero pos/leak, possibly put the original TB back, clean ALL contacts as explained on the web page below, be happy. I guess shop dropped the ball, sht happens ...if reason 1or2, they must repair it free, should not be an issue.

Re: Throttle Position Sensor/Throttle Body
Thanks for the actual advice, that is what these forums are all about.
As for the "links", I'll give them a test drive. Thanks again for the useful info and will post back the final solution, even if it is contact cleaner, elbow grease, dielectric whatever, and ball bearings. |

Re: Throttle Position Sensor/Throttle Body
well, i finally gave in and took to dealership. $75 later and an hour of my time and the mechanic fixed the issue. He said he had to "trick" the ecu. well worth the money.
