      Civic RPM Throttle body issues: Diverse reasons being given by HASS: Please help.

      The car:
      Pre-worshipped. Bought 2.5 years back at 39k kms, right now at 72k kms. Fitted BMC cold air intake and Free flow exhaust from day 1 of purchase. No major problem occurred in 2.5 years of ownership.

      Problem:
      Yellow light on the dash. Rev's not going past 2.5k in any gear.

      Diagnosis:
      HASS 1 at Gurgaon: Throttle body needs to be changed. Price quoted 45k. This is the same HASS I got my car serviced few days back, in which they did clean the throttle body and also scanned some fault codes in the ECM and did something with it (Not sure what they call it). After 10 days, this problem developed. The HASS says its regular wear and tear of throttle body. Opted for a second opinion.

      A private, competent workshop at Gurgaon: Very genuine person (owner of the workshop) told throttle body needs to be changed including the sensor which is attached to it. Quoted about 32k for it. He said its an electronic failure not a regular wear and tear. Replaced the throttle body, but the ECM yellow light was still flashing. Next, he told ECM needs to be reconfigured. Sent the ECM twice for repairs, but no luck, same problem. Then, he advised to change the ECM at Rs. 60k which was beyond my budget. It is another story that whole of this process took about 12 days. Took my car back by paying very nominal labor charges.

      HASS 2 at Noida: Contacted a senior person in office. He referred me to this HASS at Noida for a detailed diagnosis. The service manager worked on assumptions listed below:
      - Throttle body needs to be replaced.
      - The intake manifold needs to be replaced.
      - Car should be reverted to stock condition by replacing the BMC intake with stock air filter assembly and the FFE to the stock exhaust with cat con.
      - This HASS insisted that the Air intake and FFE 'might have' lead to the failure of throttle body and intake manifold, and the associated sensors 'might have' failed as well.
      - They insisted that Honda's 'Japanese' tech has perfect layouts of air filter and exhaust mechanism and must not be tampered with. They also said they will only give warranty on repairs, once the system is restored to stock condition.! They said its a mechanical + electronic failure.

      - I told them that the car is running absolutely fine during the first 10 minutes in the morning without any 'yellow light' on dashboard. Post warm up, the rpms get stuck at 2.5 k and do not go beyond. To which they have no answers.
      - It seemed more of a trial and error approach. Am not convinced.
      - They didn't bothered to check the fault codes as well telling some alien logic about how futile it is to check the fault codes at this stage,

      Need help from civic gurus out here about the possible solution.
      Can someone refer me to a competent garage who can bail me out of the situation? (In Delhi-NCR).

      I can't see myself running civic in stock condition. I enjoyed every single second of driving with the FFE and Air intake and planned to go the turbo way 1 year down the line.

      Request urgent help from Delhi ncr members.

      Check if the Civic has a MAP or MAF sensor. The sensor mostly might be the culprit.

      Before you do anything, get your ECU scanned for error codes and post the results here. Only then will we be able to help you.

      Had this same issue on my managers palio, after sales service people cleansed the throttle body and deleted some fault codes, and he got a check light on the dash on checking found its a tps failure, couldnt rev past 3k rpm, the sensors on a palio throttle body were hydraulic pressed so they couldn't be changed and the entire throttle body had to be replaced, fiat quoted 15k for replacement, we managed to get hold of one at a scarpper for 2.5k and replaced it worked brilliant and still is working, if the sensors are bolted you can try and replace them.

      Will get them posted max by day after tomorrow. Hope I can get the codes by using 'torque pro' android application using the elm interface.

      Thanks. The question in front of me is to get hold of a reliable mech in delhi who knows what he is doing.

      I too have a civic, n I plan to add a CAI n remove the catcon n add a FFE, but If something like this could happen, I think I should keep it stock. Pls do post the outcome of this issue, nn confirm if something like this could happen due to these mods.

      Lemme know the details of this competent n genuine pvt, workshop u talking about in ggn, since I too wanna know about one outside of HASS n I stay in Gurgaon too.

      Civics got both MAP and MAF sensors

      Also the I think, the components on the TB can be changed, but not sure.

      Pls post the error codes. After market air filter will not spoil the throttle body if the filter element is maintained well not to let contaminants in.

      If its the TPS problem and if the Civic has drive by wire throttle (DBW) throttle body then replacement might be the only recommended solution. I say recommended solution because thats what workshop manual of the Swift suggests - to replace the TB if TPS or TB DBW motor faulty because as per them the DBW TB is a non serviceable part (for a tech savvy & able technician the part may indeed be repairable, but finding someone like that locally may be a bit of a problem).

      P1659 is the only fault code displayed.
      Earlier there were many, but now only this remains.
